Description

  The present invention relates to a welding condition management terminal and system for managing welding conditions for piping.

Special gases are required in the process of manufacturing semiconductors. For this reason, in the semiconductor manufacturing factory, piping construction for supplying gas from the gas supply source placed in the factory to the semiconductor manufacturing apparatus is performed. Here, semiconductor manufacturing is performed in a clean room in order to prevent dust (particles) causing semiconductor defects, and the presence of particles in the gas in the supply source (cylinder, liquefaction storage tank) is also inspected. Purity management is performed.
Here, at the time of the above-described piping construction, a pipe having a fixed length of 4 m is butt-joined and TIG (tungsten inert gas) welding is performed. At that time, if the heat from the outer surface applied to the welded portion is too small, the inner surface of the pipe is not melted and a gap is generated, dust is accumulated, and particles are entrained in the semiconductor manufacturing apparatus as the gas is supplied. On the other hand, if too much heat is applied, the inner surface of the pipe is melted and the weld metal reaches the inner wall surface of the pipe to generate metal powder called fume. That is, if the piping supplied to the semiconductor manufacturing apparatus is poor, gas will be contaminated. In order to set the welding conditions in which such problems do not occur, it is necessary to confirm by looking at the width of the back wave generated on the inner surface of the pipe (the weld mark remaining on the inner surface of the pipe by welding (the part where the pipe has melted)). In the piping actually laid in the factory, since the inner surface cannot be seen, a dummy piping material (hereinafter referred to as a test piece) is used.
Conventionally, welding conditions (voltage, current, piping material, etc.) are determined while welding the test piece and checking the inner surface, and the main welding is performed so as to satisfy the conditions. FIG. 9 is a diagram for explaining test piece creation. The clamp head of the automatic welding machine 600 is attached to the joint portion of the piping materials 500a and 500b before welding, and welding is performed by inputting desired welding conditions to the test piece 500. The test piece is developed so that the back wave 503 can be confirmed. FIG. 10 is a diagram showing the pipe inner wall 502 of the test piece, and the operator confirms the welding result by looking at this. This test piece is stored and managed in a piping construction company for about 10 years.
Patent Document 1 describes a method of causing a computer to read data of results such as a groove before welding (a state of a pipe end face) and a destructive inspection after welding.

FIG. 6 is a flowchart showing an operation in which the welding condition management terminal 100 stores test identification information, welding conditions, welding location identification information, and welding construction management information. First, the server administrator who manages the management server 300 receives the welding condition management terminal 100 from the operator and connects to the communication I / F 200. Next, the sub data file in the memory 310 is requested to be transmitted from the input unit 330 of the management server 300 to the welding condition management terminal 100. In response to this, the control unit 350 of the management server 300 reads the sub data file from the memory 310, controls the communication I / F 360, and transmits it to the welding condition management terminal 100. The control unit 150 of the welding condition management terminal 100 receives the sub data file from the connection mechanism 160 via the network N.

  Hereinafter, an operation in which an operator creates a test piece and registers the welding conditions will be described. An operator creates a test piece in which two piping materials are welded, and determines optimum welding conditions. FIG. 7 is an explanatory diagram of the test piece 500 to which the barcode seal 501 is attached. The test piece 500 is for welding two pipe members 500a and 500b at a welding point P, developing the back wave 503 so that it can be confirmed, and storing it at a pipe construction company. After welding these, the operator attaches a seal 501 on which the test identification information written in the bar code is printed on the outer wall of the test piece 500 that is displaced from the welding point P as shown in FIG. Here, the seal on which the test identification information is printed is prepared in advance so that there is no seal having the same test identification information. Further, as the material, for example, a material having a pet material on the front surface and aluminum vapor deposition on the back surface is used.

  Thereafter, when the operator activates the welding condition management terminal 100, the control unit 150 of the welding condition management terminal 100 displays the title screen on the output unit 140 (step S1), and then refers to the memory 110, It is searched whether there is a sub data file (step S2). As a result of the search in step S2, if a part of the sub data file does not exist in the memory 110 among the welding condition input items, the control unit 150 of the welding condition management terminal 100 does not register “XX data”. Etc. "is displayed on the output unit 140 (step S3). The operator sees this display, connects the welding condition management terminal 100 to the communication I / F 200, and requests the input unit 330 of the management server 300 to transmit the missing sub-data file to the welding condition management terminal 100. To do. In response to this, the control unit 350 of the management server 300 reads the sub data file from the memory 310 and transmits it to the welding condition management terminal 100 via the communication I / F 360. When receiving the sub data file from the connection mechanism 160, the control unit 150 of the welding condition management terminal 100 stores it in the memory 110. Note that the sub-data file search operation in step S2 may be omitted.

  On the other hand, if all the sub-data files of the welding condition input items exist as a result of the search in step S2, the control unit 150 selects whether to start reading the barcode or to refer to the data in the memory 110. Is displayed on the output unit 140 (step S4), and an input from the input unit 130 is waited for. When waiting for input, when a selection button for barcode reading is pressed from the input unit 130, the control unit 150 waits for input from the identification information reading unit 120. Thereafter, the operator causes the barcode of the test piece 500 to be read from the identification information reading unit 120 of the welding condition management terminal 100 as shown in FIG. When a barcode is input from the identification information reading unit 120, the control unit 150 refers to the memory 110 to determine whether or not the test identification information indicated by the input barcode is registered, that is, the test identification information is stored in the memory. It is determined whether or not it exists at 110 (step S5). If it has not been registered, that is, if the input test identification information does not exist in the memory 110, the control unit 150 displays a new registration screen and registers the welding condition information of the test piece 500 or the piping. A selection screen for registering the welding operation management information of the welding part is displayed on the output unit 140 (step S6), and input from the input unit 130 is waited for. The operator views the display of the output unit 140 and selects the welding condition information registration of the test piece 500 from the input unit 130. The control unit 150 of the welding condition management terminal 100 receives input data from the input unit 130 and determines the selection content (step S7). When the control unit 150 determines that the input data indicates registration of the welding condition information of the test piece 500, the control unit 150 displays a new test piece registration screen on the output unit 140 (step S8) and waits for input of welding condition information. .

  In this case, the control unit 150 causes the output unit 140 to display an input field for each item of the above-described welding conditions. When the operator selects one of the input fields of the welding condition item displayed on the output unit 140 from the input unit 130, the control unit 150 reads out the sub data file corresponding to the item from the memory 110, and this The selection items stored in the sub data file are displayed on the output unit 140. This process may not be performed. Then, the operator looks at the display of the output unit 140, inputs welding condition information regarding the test piece 500 from the input unit 130, and presses the registration button of the input unit 130.

  When receiving the welding condition information and the registration request from the input unit 130, the welding condition writing unit 151 of the welding condition management terminal 100 registers the information in association with the test identification information received in step S5, that is, stores it in the memory 110 (step 110). S9). Next, the control unit 150 causes the output unit 140 to display an inquiry as to whether or not to continue registration of the welding condition information of the test piece 500. The operator sees the display on the output unit 130 and makes a desired input from the input unit 130. The control unit 150 determines whether the input data received from the input unit 130 is a request to continue registration (step S10). If the input data is a request to continue registration, the process proceeds to step S8 and the process is repeated. On the other hand, if the input data is not a request to continue registration, the process ends.

Below, the operation | movement which stores welding information in the management server 300, transmits a welding condition from the management server 300 to the other welding condition management terminal 100, and is shared after that is demonstrated. The server administrator receives the welding condition management terminal 100 from the worker who created the test piece and connects to the communication I / F 200. And the request which reads the welding condition information stored in the welding condition management terminal 100 from the input part 330 of the management server 300 is made. The terminal information receiving unit 351 of the management server 300 controls the communication I / F 360 and requests the welding condition management terminal 100 for welding condition information. When the control unit 150 of the welding condition management terminal 100 receives this, the welding condition reading unit 152 reads the welding condition information from the memory 110 and transmits it to the management server 300. The terminal information receiving unit 351 of the management server 300 stores the received welding condition information in the memory 310.
Then, the server administrator receives each welding condition management terminal 100 from a plurality of workers who perform pipe welding, connects to the communication I / F 200 before pipe welding, and stores the memory from the input unit 330 of the management server 300. The welding condition information in 310 is requested to be transmitted to the welding condition management terminal 100. The terminal information transmission unit 352 of the management server 300 reads out the welding condition information from the memory 310 and transmits it to the welding condition management terminal 100. The control unit 150 of the welding condition management terminal 100 stores the received welding condition information in the memory 110. Thereafter, the server administrator similarly connects the plurality of welding condition management terminals 100 to the management server 300 to repeat the above-described processing, and returns them to the plurality of workers.
Thereby, a plurality of workers can share welding conditions. In addition, when the welding condition information needs to be corrected, the correction content can be shared by correcting the welding condition information of the management server 300.

Next, an operation in which an operator registers welding construction management information at the time of piping in a factory will be described. Before starting welding, the worker refers to the welding conditions stored in the welding condition management terminal 100 as described above, and performs the pipe welding work according to the welding conditions.
The operator inquires the operator who created the test piece for the test identification information corresponding to the piping location in charge. And an operator starts the welding condition management terminal 100 which he has, and performs the process of above-mentioned step S1-S4. Thereafter, when the control unit 150 is waiting for input, the operator presses a data reference selection button from the input unit 130. The control unit 150 receives input data indicating data reference selection from the input unit 130, displays information stored in the memory 110, that is, a list of test identification information on the output unit 140 (step S31). A selection button is displayed in the column. When the operator presses one of the selection buttons in the list from the input unit 130, the welding condition information corresponding to the selected test identification information is read and displayed on the output unit 140 (step S21). The worker visually recognizes the displayed welding conditions and performs the welding operation of the pipes accordingly.

  In the welding operation, the operator puts a bar code seal indicating the welding location identification number at a position shifted from the welding location, as in the case of the test piece of FIG. Here, this seal is created in advance so that there is no seal having the same weld location identification information. Thereafter, the operator presses the menu button of the input unit 130, and the welding condition management terminal 100 transitions to step S4. And the barcode stuck on the welding location of piping is read from the identification information reading part 120 of the welding condition management terminal 100, and the control part 150 determines the input identification information. Thereafter, the selection screen display in step S6 is performed in the same manner as described above. The operator sees the display on the selection screen of the output unit 140 and selects the registration of the welding construction management information of the welding part from the input unit 130. The control unit 150 of the welding condition management terminal 100 performs the same process as in step S7 described above, and determines that the input data is data indicating registration of welding construction management information of the welding location. And the control part 150 displays the new registration screen for piping welding locations on the output part 140 (step S11), and waits for the input of welding construction management information.

At this time, similarly to the above-described step S8, the control unit 150 causes the output unit 140 to display the input fields of each item of the above-described welding construction management information, and the operator visually recognizes this and inputs from the input unit 130. Select one of the columns. The control unit 150 reads the sub data file corresponding to the item from the memory 110 and displays the selection item stored in the sub data file. This process may not be performed.
Then, the operator sees the display on the output unit 140, inputs welding construction management information such as test identification information, welding worker name, and welding date from the input unit 130, and presses a registration button on the input unit 130.

  Next, the welding construction management information writing unit 153 of the welding condition management terminal 100 receives the welding construction management information and the registration request from the input unit 130 as in step S9 described above, and the welding location identification information received in step S5. Corresponding welding construction management information is registered, that is, stored in the memory 110 (step S12). Thereafter, similarly to the processing for the welding condition information in step S10 described above, the control unit 150 causes the output unit 140 to display an inquiry as to whether or not to subsequently register welding construction management information, and accepts input data from the input unit 130. Is a request to continue registration (step S13). If the input data is a request to continue registration, the process proceeds to step S11 to repeat the process. On the other hand, if the input data is not a request to continue registration, the process ends.

  Thereafter, the worker registers welding construction management information in the same manner as described above every time welding work is performed at another welding point. Each time the welding conditions such as the time zone change, a test piece 500 is created and a new welding condition is input to the welding condition management terminal 100, and the welding condition management terminal 100 registers new welding condition information. The operator displays new welding conditions on the welding condition management terminal 100, performs piping according to the new welding conditions, and inputs welding construction management information of a new welding location. The welding condition management terminal 100 registers new welding construction management information.

Thereafter, when the server administrator receives each welding condition management terminal 100 from a plurality of workers, the server administrator connects to the communication I / F 200 and performs the same welding operation as the operation of storing the above-described welding condition information in the management server 300. The construction management information is stored in the management server 300. Thereafter, the server administrator receives the welding condition management terminals 100 from a plurality of inspectors, connects them to the communication I / F 200, and stores the welding operation management information in each of the inspectors' welding condition management terminals 100.
Thereby, welding construction management information can be shared between a plurality of workers and a plurality of inspectors. Further, when the welding construction management information needs to be corrected, the correction contents can be shared by correcting the welding construction management information of the management server 300.

Next, an operation in which an inspector inspects a welding location and registers appearance inspection data using the welding condition management terminal 100 will be described.
First, the inspector activates the welding condition management terminal 100 possessed, performs the above-described processing of steps S1 to S4, and selects barcode reading from the input unit 130. Thereafter, as shown in FIG. 7, the inspector causes the bar code of the welding portion to be read from the identification information reading unit 120 of the welding condition management terminal 100. The control unit 150 similarly performs the process of step S5 described above, and determines that it is stored in the memory 110. Thereafter, when the control unit 150 determines that the identification information is the welding location identification information, the welding execution management information reading unit 154 reads out the welding execution management information corresponding to the input welding location identification information from the memory 110. Is displayed on the output unit 140 (step S21).

  Here, the welding operation management information reading unit 154 displays the welding operation management information on the output unit 140 and at the same time displays the “reference appearance inspection data” button and the “appearance inspection data input” button on the output unit 140. The inspector presses the “appearance inspection data input” button from the input unit 130 after viewing the display of the welding construction management information on the output unit 140. The control unit 150 of the welding condition management terminal 100 causes the output unit 140 to display a screen for inputting appearance inspection data (for example, a screen of appearance inspection result table showing inspection items in a table) and a registration button. Wait for input.

  Then, the inspector looks at the display of the output unit 140, and adds the result of the appearance inspection of the welded portion of the pipe (for example, the inspection result of the inspection item related to the welding failure such as the presence or absence of misalignment) and the welding inspector name. Input from the input unit 130 and press the registration button. When receiving the inspection result data and the welding inspector name from the input unit 130, the control unit 150 of the welding condition management terminal 100 stores them in the memory 110 in association with the welding location identification information. At this time, the welding construction management information writing unit 154 writes the input welding inspector name in the welding construction management information associated with the same welding location identification information.

Thereafter, the server administrator receives the welding condition management terminal 100 from each of the plurality of inspectors, connects to the communication I / F 200, and stores the inspection result data in the management server 300. Next, each welding condition management terminal 100 is received from a plurality of workers and connected to the communication I / F 200, and the management server 300 stores the inspection result data in the welding condition management terminal 100. Thereafter, the server administrator returns the welding condition management terminal 100 to the worker.
As a result, the welding construction management information can be shared between a plurality of workers and the inspector, so that the operator can re-weld the welding location where the inspection result of the welding failure is indicated. . In addition, when the inspection result data needs to be corrected, the correction contents can be shared by correcting the inspection result data of the management server 300.

  Below, the case where an operator refers to the appearance inspection data of the welded part that has been welded poorly as a result of the inspection by the inspector will be described. The worker activates the welding condition management terminal 100 in the same manner as when the inspector referred to the welding construction management information described above, performs the above-described steps S1 to S4, and reads the barcode from the input unit 130. select. Then, the barcode of the welding location is read from the identification information reading unit 120 of the welding condition management terminal 100. The control unit 150 of the welding condition management terminal 100 similarly performs the process of step S5 described above, and determines that the identification information indicated by the input barcode is stored in the memory 110. Thereafter, the control unit 150 determines that the identification information indicated by the bar code is the welding location identification information, and the welding construction management information reading unit 154 reads from the memory 110 the welding construction corresponding to the input welding location identification information. The management information is read out and displayed on the output unit 140 (step S21). FIG. 8 is an example of a result of displaying the welding construction management information by the output unit 140 of the welding condition management terminal 100. Here, the welding part identification information, the welding date, the test identification information, the welding operator name, and the welding inspector name are displayed on the output unit 140 of the welding condition management terminal 100, respectively. The output unit 140 also displays the above-described “appearance inspection data reference” button and “appearance inspection data input” button. The operator sees this display and presses the “reference appearance inspection data” button from the input unit 130. The control unit 150 of the welding condition management terminal 100 reads the inspection result data of the corresponding welding location identification information from the memory 110 and displays it on the output unit 140 together with the “OK” button (step S22). The operator confirms the inspection result data by looking at the display on the output unit 140. Then, when the above operation is repeated and inspection result data in which a welding defect is recorded is visually recognized, welding is performed again. Thereafter, an “OK” button is pressed from the input unit 130. In response to this, the control unit 150 of the welding condition management terminal 100 ends the process. At this time, the welding condition management terminal 100 transitions to the above-described step S21, displays the welding operation management information, and simultaneously displays the edit button. When the operator presses the edit button, the new welding operation management information is displayed. The welding construction management information may be rewritten when is input.

  Then, the welding condition information, welding construction management information, and inspection result data stored in the management server 300 are output to the output device 400. At this time, for example, the control unit 350 of the management server 300 outputs welding condition information, welding construction management information, and inspection result data in a predetermined format. This makes it possible to create a work report, a document that meets the requirements of the ISO (International Organization for Standardization) standard, and the like, thereby reducing the work of the worker.

  As described above, the test identification information given to the test piece used for the welding test is read, the identification information and the welding condition information of the test piece are associated with each other and written in the memory 110, and the written welding condition information is output to the output unit. 140, the welding location identification information given to the welding location of the pipe welded in accordance with the welding condition information is read, and the welding location management information including the welding location identification information and the test identification information is associated with each other in the memory 110. Since the written and written welding construction management information is displayed on the output unit 140, it is possible to grasp the welding location of the piping and the welding conditions at the time of the welding in association with each other. As a result, even if it seems that the welding conditions are optimal at the time of construction, it is likely to deteriorate when better conditions are found with the subsequent technological development or when certain conditions such as the nature of the gas used are met. When it becomes clear, it can be determined which line of which customer corresponds, so that the piping construction can be performed again and improved, and the quality of the piping construction can be guaranteed.

  Moreover, since the unique information at the time of pipe welding is stored in the welding construction management information, it becomes possible to grasp various welding situations.

  In the above-described embodiment, the welding condition information, the welding construction management information, and the inspection result data are stored in the management server 300. However, the welding condition management terminal 100 may be operated stand-alone without being stored.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes a design and the like within the scope not departing from the gist of the present invention.
