For example, when the work list includes N pieces of work information (N: an integer equal to or greater than 2), the processor 31 selects work information whose order information assigned to each piece of work information of a plurality of works is first. Then, the work indicated by this first work information is determined to be the work currently being worked on by the operator. The processor 31 changes the color of the display area corresponding to the first work among the works included in the work list screen SC2 (for example, the welding condition display area WC12 and the welding output number display area CT12 shown in FIG. 5) into a first color. A work list screen SC2 changed to is generated and displayed on the display section 33. When the processor 31 determines that the number of welding outputs of the work being worked on is equal to the number of welding outputs included in the first work information, the processor 31 displays a display corresponding to the first work among the works included in the work list screen SC2. A work list screen SC2 in which the color of the areas (for example, welding condition display area WC11 and welding output number display area CT11 shown in FIG. 5) are changed from the first color to the second color is generated and displayed on the display unit 33. .

The processor 31 repeatedly executes the process described above, and if it is determined that the number of welding outputs of the workpiece being worked on is equal to the number of welding outputs included in the Nth workpiece information, the processor 31 selects one of the works included in the worklist screen SC2. Generates a work list screen SC2 in which the color of the display area corresponding to the Nth work (for example, welding condition display area WC11 and welding output frequency display area CT11 shown in FIG. 5) is changed from the first color to the second color. By displaying this on the display unit 33, the operator is notified that all the works included in the work list have been completed.

The memory 32 includes, for example, a RAM as a work memory used when executing the processing of the processor 31, and a ROM that stores a program that defines the processing of the processor 31. Data generated or acquired by the processor 31 is temporarily stored in the RAM. A program that defines the processing of the processor 31 is written in the ROM.

Note that the input unit 34 may be realized as a touch panel configured integrally with the display unit 33.

The motor circuit 35 acquires a control command regarding the feeding of the welding wire output from the processor 31. The motor circuit 35 drives the motor based on the acquired control command to cause the feeding device T1 to feed the welding wire.

Welding output circuit 36 is controlled by processor 31 to perform welding output to the welding torch. Welding output circuit 36 adjusts welding output based on control information regarding welding power (welding current, welding voltage) included in the welding condition parameters output from processor 31. The welding output circuit 36 outputs welding output to the welding torch based on the operator's operation of the torch switch of the welding torch. Further, the welding output circuit 36 outputs the welding output result to the welding torch to the processor 31.

It may be. In such a case, the terminal device 100A may be able to execute various functions executed by each of the terminal device P1 and the memory device MM1. Further, the terminal device 100A may be a so-called cloud server.

In addition, in the example shown in FIGS. 1 and 2, the memory device MM1 and the welding output device PS1 have been described as being configured as separate bodies, but for example, the welding output device PS1 may be configured integrally by one computer. It may be the device 100B. In such a case, welding output device 100B may be able to execute various functions performed by each of memory device MM1 and welding output device PS1.

Next, with reference to FIG. 3, the operating procedure of the welding work support system 200 according to the first embodiment will be described. FIG. 3 is a sequence diagram showing an example of the operation procedure of the welding work support system 200 according to the first embodiment. Note that when the terminal device P1 and the memory device MM1 are integrally configured in the terminal device 100A, the terminal device 100A can execute each process executed by the terminal device P1 and the memory device MM1 shown in FIG. It may be. Similarly, in the case where the memory device MM1 and the welding output device PS1 are integrally configured in the welding output device 100B, the welding output device 100B is executed by the memory device MM1 and the welding output device PS1 shown in FIG. Each process may be executable.

The terminal device P1 accepts a work list input operation performed by a predetermined worker (St1). Note that the work list here is information including information on work to be performed by a predetermined worker. The terminal device P1 transmits the input work list information to the memory device MM1 (St2).

The memory device MM1 acquires the work list information transmitted from the terminal device P1. The memory device MM1 collates the acquired work list information with each piece of work information stored in the welding condition table TB. The memory device MM1 extracts each piece of work information included in the acquired work list from among the plural pieces of work information stored in the welding condition table TB (St3). When the welding output device PS1 receives an operation by the operator via the input unit 34 to request the display of a worklist screen SC2 (see FIG. 5) that includes information on a predetermined worklist, the welding output device PS1 requests information on this worklist. A control command is generated and transmitted to the memory device MM1. The memory device MM1 provides the welding output device PS1 with work list information including each piece of work information included in the extracted work list based on a control command requesting the work list information transmitted from the welding output device PS1.

The welding output device PS1 generates a work list screen SC2 (see FIG. 5) that displays a list of the work to be performed by the worker and the welding conditions for the work, based on the work list information transmitted from the memory device MM1. and is displayed on the display section 33 (St5).

The welding output device PS1 counts the number of welding outputs for the workpiece that the operator is currently working on, based on the operation result of the welding torch by the operator (that is, the welding output result to the welding torch by the welding output circuit 36). The work list screen SC2 is updated and displayed on the display unit 33 based on the current number of welding outputs of the workpiece (St7). The welding output device PS1 associates the work information of the work included in the work list with the information on the number of welding outputs of the work performed by the worker and transmits the result to the memory device MM1 as the result of the work done by the worker (St8 ).

Specifically, in the process of step St7, the welding output device PS1 determines whether the number of welding outputs of the workpiece being worked by the operator is equal to the number of welding outputs included in the workpiece information. If the welding output device PS1 determines that the number of welding outputs for the workpiece that the worker is working on is equal to the number of welding outputs included in the workpiece information of the workpiece, the welding output device PS1 displays a message for the workpiece that is currently being worked on in the work list screen SC2. The corresponding display areas (for example, welding condition display area WC11 and welding output number display area CT11 shown in FIG. 5) are changed from the first color to the second color, and the welding output displayed in the welding output number display area is A work list screen SC2 with the number of times incremented is generated and displayed on the display section 33. On the other hand, if the welding output device PS1 determines that the number of welding outputs for the workpiece that the worker is currently working on is not equal to the number of welding outputs included in the work information of the workpiece, the welding output device PS1 outputs a A work list screen SC2 is generated and displayed on the display unit 33 while leaving the display area corresponding to the workpiece in the first color and incrementing the number of welding outputs displayed in the welding output number display area.

The memory device MM1 associates the work information included in the work list transmitted from the welding output device PS1 with the information on the number of welding outputs performed by the worker, and stores it in the welding condition table TB or memory 22 as the work record by the worker. (St9). Thereby, the memory device MM1 can manage the work results performed by the worker.

The number of welding outputs to be performed is "25", the welding command value "280A, 24.0V" which is the welding torch control information (welding conditions), the base metal material "mild steel", the plate thickness "20mm", the wire information "1" .2", joint "fillet", welding method (welding method) "CO2", waveform "1", etc., and accepts editing operations regarding these workpiece information by the operator.

When the send button BT1 is pressed (selected) based on the operator's operation, the processor 11 transfers the work information of the work stored in the welding condition table TB to the edited work displayed on the work list editing screen SC1. Generates a control command to update the information. The processor 11 associates the generated control command with the edited work information and transmits it to the memory device MM1. The memory device MM1 updates the work information of the work stored in the welding condition table TB to the edited work information based on the control command transmitted from the terminal device P1.

It is displayed including each of WC13, WC14, and WC15, and each of welding output frequency display areas CT11, CT12, CT13, CT14, and CT15 that display the number of welding outputs for each workpiece performed by the operator.

When any one work selection button is pressed (selected) based on operator operation, the processor 31 controls welding power (welding current, control information regarding the welding voltage) is generated and output to the welding output circuit 36. Based on the operator's operation of the torch switch of the welding torch, the processor 31 drives the welding output circuit 36 to start welding output to the welding torch, and also counts the number of welding outputs for the currently selected workpiece.

The processor 31 counts (increments) the number of welding outputs of the workpiece based on the welding output result output from the welding output circuit 36, and displays the counted current number of welding outputs in the welding output number display area.

The processor 31 determines whether the current counted number of welding outputs is equal to the number of welding outputs information included in the workpiece information of the workpiece. For example, when the work selection button BT31 is pressed (selected) by the worker and the current counted number of welding outputs is 25, the processor 31 displays the welding condition display area WC11 and the welding output number display area CT11. A work list screen SC2 in which the first color (for example, yellow, etc.) is changed to a second color (for example, orange, etc.) is generated and displayed on the display unit 33.

On the other hand, the processor 31 determines whether the current counted number of welding outputs is equal to the number of welding outputs information included in the workpiece information. For example, when the workpiece selection button BT32 is pressed (selected) by the worker and the current counted number of welding outputs is 6, the processor 31 displays the welding condition display area WC12 and the welding output number display area CT12. remains at the first color (eg, yellow, etc.).

In the first embodiment, the welding condition display area and Although an example of the welding work support system 200 that changes the welding output frequency display area from the first color to the second color has been described, the present invention is not limited thereto. The welding work support system 200 may change the color to three or more in stages based on the current counted number of welding outputs. For example, when the welding work support system 200 determines that the progress status of the workpiece exceeds a predetermined threshold (for example, 50%, 60%, etc.), the welding work support system 200 changes the first color to the third color and When it is determined that the progress has reached 100%, the third color may be changed to the second color.

As explained above, the welding work support system 200 according to the first embodiment is capable of communicating with the welding output device PS1 that controls the welding output corresponding to the welding conditions for welding the welding object, and the welding output device PS1. A memory device MM1 (an example of a storage device) is provided, which stores a work list that includes workpieces associated with welding conditions for welding objects to be welded. Memory device MM1 transmits the work list to welding output device PS1. The welding output device PS1 displays a worklist screen SC2 including the transmitted worklist, counts the number of outputs of welding output corresponding to the welding conditions included in the worklist, and displays the counted number of outputs and the welding conditions. If it is determined that the counted number of outputs and the number of welding outputs included in the number of welding outputs are equal, a work list screen SC2 is generated that highlights the workpieces corresponding to the welding conditions. and output it.

As a result, the welding work support system 200 according to the first embodiment determines that this work has been completed when the number of welding outputs corresponding to the workpiece performed by the operator is equal to the number of welding outputs included in this workpiece information. It is possible to generate a work list screen SC2 in which completed works are highlighted and output to the display section 33. On the work list screen SC2, the worker can see at a glance the number of welds that correspond to the work currently being worked, the number of welds that have been welded, and the number of welds that have been completed, among the work that the worker should do. It can be confirmed. Therefore, the welding work support system 200 can suppress deterioration in welding quality due to excess or deficiency in the number of welds.
