Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-4 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The embodiment of the application provides an intelligent welding method based on a gas shielded welding machine, and the method can be applied to the gas shielded welding machine or can be realized by a management center of the gas shielded welding machine. The gas shield welding machine can be a welding machine which utilizes gas for protection during welding and isolates air outside a welding area so as to prevent the oxidation of the welding area, wherein carbon dioxide, argon or helium and mixed gas of three gases can be selected as protective gas, and the gas shield welding machine can be an electric welding machine utilizing an inversion principle. As shown in fig. 1, the gas-shielded welding machine may include a power supply, a wire feeding structure, a welding gun, a gas supply structure, and a controller, wherein the power supply may be configured to provide current and voltage for welding, the wire feeding structure may be configured to continuously output a welding wire to a welding site during welding, the welding gun may be configured to fix the welding wire and output shielding gas, and is held by an operator to continuously adjust a welding position, the gas supply structure may be configured to provide the shielding gas during welding, and the controller may be configured to control start and stop of the gas-shielded welding machine, and adjust parameters of a welding process. In this embodiment, a management center may be provided for a plurality of gas-shielded welding machines, and each gas-shielded welding machine may be controlled by the management center.
The following will describe in detail the process flow of fig. 2, which is executed by a single gas-shielded welding machine, with reference to the following embodiments:
and 201, receiving a starting request of the target gas shielded welding machine input by a user, and acquiring task parameters of a target welding task.
The target gas shielded welding machine can be any available gas shielded welding machine, and the task parameters at least comprise the attributes of the welded piece, the attributes of the welding wire, the welding mode and the welding structure.
In implementation, when a constructor uses a gas shielded welding machine to complete a target welding task, the constructor can select one target gas shielded welding machine for welding and input a starting request on the target gas shielded welding machine. Meanwhile, the constructor can input task parameters of a target welding task on the target gas shielded welding machine, such as the thickness and the material of a welded piece, the diameter and the material of a welding wire are selected, the welding mode is flat welding, vertical welding or overhead welding, and the welding structure is butt joint, lap joint, angle joint and the like. Or the constructor can search and select the recorded task parameters of the target welding task from a welding task storage catalog of the target gas shielded welding machine. The target gas shielded welding machine may then obtain the task parameters for the target welding task after receiving the start request.
202, obtaining a target welding record corresponding to the task parameter from a historical welding record of a target gas-shielded welding machine prestored locally.
In implementation, after acquiring the task parameters of the target welding task, the target gas-shielded welding machine may first retrieve a local pre-stored historical welding record of the local machine, and search for a target welding record corresponding to the task parameters in the historical welding record, that is, search for a target welding record with the same task parameters. It will be appreciated that a gas shielded welding machine may generate a weld record each time a welding task is performed and store corresponding task parameters.
And 203, calling and loading the welding process parameters of the target welding record.
The welding process parameters at least comprise output voltage, output current, a welding wire moving path, moving speed and an inclination angle.
In practice, each time the gas shielded welding machine performs a welding task and generates a corresponding welding record, the gas shielded welding machine may simultaneously store welding process parameters of the welding task in the welding record, where the welding process parameters may include at least an output voltage, an output current, a wire moving path, a moving speed, and an inclination angle. Furthermore, the actual values of all welding process parameters at different moments in the whole welding task process can be recorded in the form of a plurality of numerical value change curves. Specifically, the output voltage and the output current can be measured by a voltage and current detection component arranged in the gas shielded welding machine, the moving path and the moving speed of the welding wire can be measured by a displacement sensor arranged in the welding gun, and the inclination angle of the welding wire can be measured by a gyroscope arranged in the welding gun. Therefore, after the target welding record is found, the target gas shielded welding machine can call and load the welding process parameters of the target welding record.
And 204, acquiring the auxiliary level of the welding task input by the user, and setting the range of the welding parameters according to the auxiliary level of the welding task and the welding process parameters.
In practice, gas shielded welding machines can give different levels of welding assistance to different constructors, taking into account that different constructors have different welding technologies. Therefore, after the target gas shielded welding machine receives the starting request, options corresponding to a plurality of welding task auxiliary levels can be provided for the constructor, for example, five welding task auxiliary levels from beginner, amateur, general, skilled and exquisite can be set, if the constructor is relatively sparsely in welding technology, the beginner level can be selected, and if the constructor is relatively skilled in welding technology, the higher level can be selected step by step. Therefore, the target gas shielded welding machine can obtain the auxiliary level of the welding task input by the user, and set the range of the welding parameters according to the auxiliary level of the welding task and the welding process parameters. Specifically, the higher the auxiliary level of the welding task, the less the gas shielded welding machine has to limit the welding process, so the larger the welding parameter range can be set, and conversely, the smaller the welding parameter range can be set. For example, if the average moving speed of the welding wire is 5mm/s, the welding parameter range can be set to 4.5-5.5mm/s for the novice level, and set to 3-7mm/s for the proficiency level.
In executing the target welding task, 205, the execution of the target welding task is adjusted based on the welding parameter range.
In implementation, after the target gas-shielded welding machine determines the welding parameter range corresponding to each welding process parameter, when a constructor executes a target welding task by using the target gas-shielded welding machine, the execution process of the target welding task can be adjusted based on the welding parameter range.
It should be noted that the welding process parameters recorded in the gas-shielded welding machine are substantially used for assisting the constructors unskilled in the welding technology to weld, so that the welding process of the constructors skilled in the welding technology can be selected only for recording, that is, the welding process parameters in the subsequent welding process are recorded and stored only when the constructors select a high-level auxiliary level of the welding task.
It should be noted that, for one welding task, there may be a plurality of welding conditions (for example, there are two welding structures of fillet welding and butt welding, or there are two welding methods of flat welding and vertical welding, etc.), each welding condition has its own corresponding task parameter, so in the historical welding record, different welding process parameters may be recorded for different welding conditions under the same welding task. Correspondingly, when the constructor inputs the task parameters of the welding task, the constructor can respectively input the corresponding task parameters according to various welding conditions. In the actual welding process, the conversion of the welding condition can be manually operated by constructors or automatically detected by a gas shielded welding machine, and the gas shielded welding machine can automatically change the loaded welding process parameters at the same time after the conversion of the welding condition occurs.
For step 202, different weld record review authorities may be set for different users, and the corresponding process may be as follows: acquiring identity authentication information input by a user, and determining a welding capacity attribute corresponding to the user; screening available historical welding records corresponding to a user from all historical welding records of a target gas-shielded welding machine prestored locally according to the welding capacity attribute; and acquiring a target welding record corresponding to the task parameter from the available historical welding records.
In implementation, the constructor can input the identity authentication information of the constructor when requesting to start the target gas shielded welding machine. After the target gas-shielded welding machine acquires the identity authentication information, the welding capability attribute corresponding to the constructor can be determined, the welding capability attribute can be specifically an attribute value reflecting the welding capability, the stronger the welding capability is, the higher the attribute value is, and the welding capability attribute can be recorded into the target gas-shielded welding machine after the constructor is evaluated by a manager. Furthermore, considering that constructors with different welding capabilities have different welding technologies, and constructors with weaker welding capabilities are difficult to master some advanced welding processes, different consulting authorities of historical welding records can be set for constructors with different welding capability attributes, and the consulting authorities can be set for each historical welding record one by a manager after evaluating each historical welding record. Therefore, after the welding capacity attribute corresponding to the constructor is determined, the target gas-shielded welding machine can screen out the available historical welding records corresponding to the constructor from all the historical welding records of the target gas-shielded welding machine prestored locally according to the welding capacity attribute. Therefore, the target gas shielded welding machine can search the target welding record corresponding to the task parameter of the target welding task in all available historical welding records.
For step 205, the welding process may be adjusted by means of alarm and policy prompting, and the corresponding processing may be as follows: detecting actual values of all welding process parameters in real time when a target welding task is executed; and when the actual value of the target welding process parameter exceeds the welding parameter range, triggering a welding violation alarm and providing a welding process adjustment strategy for a user.
The target welding process parameter is any welding process parameter in the welding process.
In implementation, when a constructor executes a target welding task by using the target gas-shielded welding machine, the target gas-shielded welding machine can detect actual values of various welding process parameters in real time, and compare the detected actual values with welding parameter ranges corresponding to the various welding process parameters. When the actual value of the target welding process parameter is detected to exceed the welding parameter range, it is judged that the current welding operation has a problem, and a welding violation alarm can be triggered, such as sending out a warning sound or flashing a warning lamp. Meanwhile, a welding process adjusting strategy can be provided for constructors in a voice broadcasting or text display mode according to the actual value and the welding parameter range, for example, when the moving speed of the welding wire is too high, the welding process adjusting strategy can be used for reducing the moving speed of the welding wire.
Further, when the actual value of the welding process parameter greatly deviates from the range of the established welding parameter, the machine can be stopped immediately, and the following treatment can be correspondingly carried out: and when the actual value of the target welding process parameter is detected to exceed the welding parameter range and the exceeding amplitude is larger than the preset amplitude threshold value, closing the target gas shielded welding machine.
In implementation, when the target gas-shielded welding machine detects various welding process parameters in real time in the welding process, if the actual values of the target welding process parameters are detected to exceed the selected welding parameter range and the exceeding amplitude is greater than the preset amplitude threshold value, it can be determined that the current welding process needs to be stopped immediately, and therefore the target gas-shielded welding machine can be triggered to be closed. It can be understood that from welding process parameters such as output voltage, output current, welding wire moving path, moving speed and inclination, when the actual value of welding process parameter appears by a wide margin the deviation, if continue present welding state, will seriously influence welding quality, engineering accident may even appear, cause equipment to damage casualties scheduling problem, so trigger target gas shield welding machine at this moment and close immediately, can improve welding task's execution security by a wide margin to can guarantee welding quality to a certain extent.
In another embodiment, the effect of the environmental parameters on the welding process may be considered when setting the welding parameter range, and the corresponding process may be as follows: the method comprises the steps of obtaining environmental parameters of the current construction environment, and adjusting the welding parameter range according to the environmental parameters, wherein the environmental parameters at least comprise temperature, humidity and air flow rate.
In implementation, an environmental parameter detection unit can be arranged on the target gas-shielded welding machine, and specifically, the target gas-shielded welding machine can comprise a temperature sensor, a humidity sensor and an air flow rate detector, and the environmental parameter of the current construction environment can be acquired through the environmental parameter detection unit. Thus, after step 204, the target gas-shielded welding machine may adjust the set welding parameter range according to the environmental parameter to set a welding parameter range matching the environmental parameter. Specifically, the adjustment of the welding parameter range may be obtained by combining actual construction experience with theoretical derivation, and is not specifically limited in this embodiment.
In another embodiment, the welding process parameters may be adjusted according to the actual welding result, and the corresponding process may be as follows: detecting an actual welding result of a target welding task, and acquiring a standard welding result of welding process parameters; and comparing the actual welding result with the standard welding result, and adjusting the welding process parameters of the target welding record according to the comparison result.
In implementation, after the target welding task is completed, the gas shielded welding machine can detect an actual welding result of the target welding task, and simultaneously can obtain a standard welding result corresponding to the loaded welding process parameters, and then can compare the actual welding result with the standard welding result. Specifically, the actual welding result can be detected by image shooting or ultrasonic induction, and the comparison process can be comparison of the width and the width of a welding seam, the height of the welding seam, the edge neatness degree and the surface smoothness degree, the depth of fusion, the existence of air holes and the like. Therefore, after the comparison is completed, the gas shielded welding machine can adjust the welding process parameters of the loaded target welding records according to the comparison result, for example, if the welding seam is narrow, the penetration depth is small and the residual height is small in the actual welding result, the welding wire can be judged to be too fast in moving speed, and the moving speed of the welding wire can be properly reduced.
In another embodiment, if there is no welding record corresponding to the task parameter in the current gas-shielded welding machine, the welding record may be searched in a welding record stored in a similar gas-shielded welding machine, and the corresponding process may be as follows: if no target welding record corresponding to the task parameter exists in the historical welding records of the target gas-shielded welding machine prestored locally, determining a similar gas-shielded welding machine according to the equipment attribute information of the target gas-shielded welding machine; and acquiring historical welding records of the similar gas-shielded welding machine from the management center, and acquiring target welding records corresponding to the task parameters from the historical welding records of the similar gas-shielded welding machine.
In implementation, after the target gas-shielded welding machine acquires the task parameters of the target welding task, the target welding record corresponding to the task parameters can be searched in the historical welding record of the target gas-shielded welding machine which is pre-stored locally. If the target gas-shielded welding machine is not found, the similar gas-shielded welding machines with the models, the factory batches, the service lives and other values similar to those of the target gas-shielded welding machine can be determined according to the attribute information of the target gas-shielded welding machine. Furthermore, the target gas-shielded welding machine can acquire the historical welding record of the similar gas-shielded welding machine from the management center, and acquire the target welding record corresponding to the task parameter from the historical welding record of the similar gas-shielded welding machine. Here, there may be a plurality of similar gas shielded welding machines, and the similar gas shielded welding machines may be divided into a plurality of levels according to the degree of similarity, and when the welding record is obtained, the similar gas shielded welding machines may be selected step by step according to the degree of similarity. Specifically, one or more similar gas shielded welding machines (which may be referred to as first-level similar welding machines for short) with the highest similarity degree may be selected first, and a target welding record corresponding to the task parameter may be searched in the historical welding records of the first-level similar welding machines. If the target welding record is not found, one or more similar gas shielded welding machines with the second highest similarity degree (namely the second-level similar welding machines) can be further found, the target welding record corresponding to the task parameter is found in the historical welding records of the second-level similar welding machines, and the like.
In another embodiment, the execution subject of the steps 201 to 204 may be a management center of the gas shielded welding machines, and as shown in fig. 3, the management center may simultaneously manage a plurality of gas shielded welding machines and store a historical welding record of each gas shielded welding machine. The management center can receive the information content input by the user, execute corresponding data processing (such as setting welding process parameters) according to the information content, and send the data processing result to the gas shielded welding machine, so that the gas shielded welding machine adjusts the welding process based on the data result. Of course, for step 205, since immediate feedback is required during the welding process, step 205 may be performed by a gas shielded welding machine to adjust the welding process.
By adopting the intelligent welding method based on the gas shielded welding machine disclosed by the application, when the gas shielded welding machine is used for welding, matched welding process parameters can be recommended to constructors according to task parameters of a welding task, so that the gas shielded welding machine can be used for carrying out auxiliary adjustment on a welding process according to the welding process parameters, and the auxiliary level of equipment can be adjusted according to the actual conditions of the constructors. Therefore, the established welding process parameters are selected for the welding task, and the gas shielded welding machine performs welding based on the welding process parameters in an auxiliary mode, so that the situation that the welding quality is poor due to insufficient personal technology and lack of experience of constructors can be greatly reduced, and the welding quality can be integrally improved.
Based on the same technical concept, the embodiment of the present application further provides an intelligent welding device based on a gas shielded welding machine, as shown in fig. 4, the device includes:
