Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings 1-4 and the embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

The embodiment of the present application provides an intelligent welding method based on a gas shielded welding machine, which can be applied to a gas shielded welding machine, or can be implemented by a management center of a gas shielded welding machine. The gas shielded welding machine can be a welding machine that uses gas for protection during welding to isolate the air from the welding area to prevent oxidation of the welding area. Carbon dioxide, argon or helium, and a mixture of the three gases can be used Gas is used as the shielding gas, and the gas shielded welding machine can be an electric welding machine using the inverter principle. As shown in Figure 1, the gas shielded welding machine can include a power supply, a wire feeding structure, a welding torch, a gas supply structure and a controller, the power supply can be used to provide current and voltage for welding, and the wire feeding structure can be used to The welding wire is continuously output to the welding place. The welding gun can be used to fix the welding wire and output the shielding gas, and it can be held by the construction personnel to continuously adjust the welding position. The gas supply structure can be used to provide shielding gas during welding, and the controller can be used to control the gas protection Start and stop the welding machine, and adjust the welding process parameters. In this embodiment, a management center can be set up for multiple gas shielded welding machines, and all gas shielded welding machines can be uniformly controlled through the management center.

Below in conjunction with the specific implementation, the execution body shown in Figure 2 is a detailed description of the processing flow of a single gas shielded welding machine, the content can be as follows:

201. Receive a start request of a target gas shielded welding machine input by a user, and acquire task parameters of a target welding task.

Wherein, the target gas shielded welding machine can be any available gas shielded welding machine, and the task parameters include at least the attributes of the workpiece to be welded, the attributes of the welding wire, the welding method and the welding structure.

In implementation, when the construction personnel use the gas shielded welding machine to complete the target welding task, they can select a target gas shielded welding machine for welding, and input a start request on the target gas shielded welding machine. At the same time, the construction personnel can input the task parameters of the target welding task on the target gas shielded welding machine, such as the thickness and material of the workpiece to be welded, the diameter and material of the welding wire selected, the welding method is flat welding, vertical welding or overhead welding, welding The structure is butt joint, lap joint, angle joint and so on. Alternatively, the construction personnel may search and select the entered task parameters of the target welding task in the welding task storage directory of the target gas shielded welding machine. Afterwards, the target gas shielded welding machine can obtain the task parameters of the target welding task after receiving the above start request.

202. Obtain the target welding record corresponding to the task parameters from the historical welding records of the target gas shielded welding machine prestored locally.

In implementation, after the target gas shielded welding machine obtains the task parameters of the target welding task, it can first call the local pre-stored historical welding records of the machine, and search for the target corresponding to the above task parameters in the historical welding records. Welding records, that is, to find the target welding records with the same task parameters. It can be understood that each time the gas shielded welding machine performs a welding task, it can generate a welding record and store corresponding task parameters.

203. Retrieve and load the welding process parameters of the target welding record.

Wherein, the welding process parameters at least include output voltage, output current, moving path of welding wire, moving speed and inclination angle.

In implementation, when the gas shielded welding machine performs a welding task and generates a corresponding welding record, it can simultaneously store the welding process parameters of the welding task in the welding record. The welding process parameters can at least include output voltage, output current, Wire moving path, moving speed and angle of inclination. Further, the actual value of each welding process parameter at different moments in the whole welding task process may be recorded in the form of multiple numerical change curves. Specifically, the output voltage and output current can be measured by the built-in voltage and current detection components of the gas shielded welding machine, the moving path and moving speed of the welding wire can be measured by the built-in displacement sensor of the welding torch, and the inclination angle of the welding wire can be measured by the built-in welding torch measured by the gyroscope. In this way, after the target gas shielded welding machine finds the target welding record, it can call and load the welding process parameters of the target welding record.

204. Obtain the welding task assistance level input by the user, and set the welding parameter range according to the welding task assistance level and the welding process parameters.

In implementation, considering that different construction personnel have different welding techniques, the gas shielded welding machine can provide different levels of welding assistance for different construction personnel. Therefore, after receiving the start request, the target gas shielded welding machine can provide construction personnel with options corresponding to multiple welding task auxiliary levels, for example, five welding tasks can be set from low to high: novice, amateur, general, proficient, and superb Auxiliary level, if the construction personnel are relatively unfamiliar with welding technology, you can choose the novice level, if the construction personnel are more skilled in welding technology, you can choose a higher level step by step. In this way, the target gas shielded welding machine can obtain the welding task assistance level input by the user, and set the welding parameter range according to the welding task assistance level and the welding process parameters. Specifically, the higher the level of welding task assistance, the less restrictions the gas shielded welding machine has on the welding process, so a larger welding parameter range can be set, and vice versa, a smaller 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 the welding parameter range can be set to 3-7mm/s for the proficient level. s.

205. When executing the target welding task, adjust the execution process of the target welding task based on the welding parameter range.

In the implementation, after the target gas shielded welding machine determines the welding parameter range corresponding to each welding process parameter, when the construction personnel use the target gas shielded welding machine to perform the target welding task, based on the welding parameter range, the target welding task The execution process is adjusted.

It is worth mentioning that the welding process parameters recorded in the gas shielded welding machine are essentially used to assist unskilled construction personnel in welding, so only the welding process of skilled construction personnel can be selected for recording. That is, only when the construction personnel selects a high-level welding task assistance level, the welding process parameters in the subsequent welding process are recorded and stored.

It should be noted that, since there may be multiple welding situations for a welding task (for example, there are two welding structures of fillet joint and butt joint, or there are two welding methods of flat welding and vertical welding, etc.), each welding situation has its own The corresponding task parameters, so in the historical welding records, different welding process parameters can be recorded for different welding situations under the same welding task. Correspondingly, when the construction personnel input the task parameters of the welding task, they can respectively input the corresponding task parameters for various welding situations. In the actual welding process, the conversion of welding conditions can be manually operated by the construction personnel, or automatically detected by the gas shielded welding machine. When the welding situation is changed, the gas shielded welding machine can automatically change the loaded welding process parameters at the same time .

For step 202, different welding record access permissions can be set for different users, and the corresponding processing can be as follows: obtain the identity authentication information input by the user, and determine the welding ability attribute corresponding to the user; Among all the historical welding records of the welding machine, filter the available historical welding records corresponding to the user; in the available historical welding records, obtain the target welding records corresponding to the task parameters.

In implementation, construction personnel can input their identity authentication information when requesting to start the target gas shielded welding machine. After the target gas shielded welding machine obtains the identity authentication information, it can determine the welding ability attribute corresponding to the construction personnel. The welding ability attribute can specifically reflect the attribute value of the welding ability. It can be set that the stronger the welding ability, the higher the attribute value , and the welding ability attribute can be entered into the target gas shielded welding machine after the manager evaluates the construction personnel. Further, considering that construction personnel with different welding abilities have different welding techniques, and it is difficult for construction personnel with weak welding ability to master some advanced welding techniques, it is possible to set historical welding records for construction personnel with different welding ability attributes Different access rights, and the access rights can also be set for each historical welding record one by one after the manager evaluates each historical welding record. In this way, after the welding ability attribute corresponding to the construction personnel is determined, the target gas shielded welding machine can filter out the available welding records corresponding to the construction personnel from all the historical welding records of the target gas shielded welding machine stored locally according to the welding ability attribute. Historical welding records. Therefore, the target gas shielded welding machine can search for the target welding record corresponding to the task parameters of the target welding task in all available historical welding records.

For step 205, the welding process can be adjusted by means of alarms and strategy prompts, and the corresponding processing can be as follows: when performing the target welding task, detect the actual values of various welding process parameters in real time; when the actual value of the target welding process parameters When the value exceeds the range of welding parameters, a welding violation alarm will be triggered, and the welding process adjustment strategy will be provided to the user.

Wherein, the target welding process parameter is any welding process parameter in the welding process.

In the implementation, when the construction personnel use the target gas shielded welding machine to perform the target welding task, the target gas shielded welding machine can detect the actual values of various welding process parameters in real time, and compare the actual values obtained by the detection with each The welding parameter ranges corresponding to the welding process parameters are compared. When it is detected that the actual value of the target welding process parameter exceeds the range of the welding parameter, it is determined that there is a problem with the current welding operation, and a welding violation alarm can be triggered, such as a warning sound or a flashing warning light. At the same time, according to the above actual values and welding parameter ranges, the welding process adjustment strategy can be provided to the construction personnel in the form of voice broadcast or text display. For example, when the welding wire moves too fast, the welding process adjustment strategy can be to reduce the welding wire moving speed .

Further, when the actual value of the welding process parameter greatly deviates from the predetermined welding parameter range, the machine can be stopped immediately, and correspondingly, the following processing can exist: when it is detected that the actual value of the target welding process parameter exceeds the welding parameter range, and the exceeding range is greater than the preset When the amplitude threshold is set, the target gas shielded welding machine is turned off.

In implementation, when the target gas shielded welding machine detects various welding process parameters in real time during the welding process, if it detects that the actual value of the target welding process parameters exceeds the range of the selected welding parameters, and the exceeding range is greater than the preset range When the threshold is reached, it can be determined that the current welding process needs to be stopped immediately, so it can be triggered to shut down the target gas shielded welding machine. It can be understood that from the perspective of welding process parameters such as output voltage, output current, welding wire moving path, moving speed and inclination angle, when there is a large deviation in the actual value of the welding process parameters, if the current welding state is continued, the welding will be seriously affected. Quality, and even engineering accidents may occur, causing equipment damage and casualties. Therefore, triggering the target gas shielded welding machine to shut down immediately at this time can greatly improve the safety of welding task execution and ensure welding quality to a certain extent.

In another embodiment, the influence of environmental parameters on the welding process can be considered when setting the range of welding parameters, and the corresponding processing can be as follows: obtain the environmental parameters of the current construction environment, and adjust the range of welding parameters according to the environmental parameters, wherein the environmental parameters Parameters include at least temperature, humidity and air velocity.

In implementation, the target gas shielded welding machine can be provided with an environmental parameter detection unit, which can specifically include a temperature sensor, a humidity sensor and an air velocity detector, and the environmental parameter of the current construction environment can be obtained through the environmental parameter detection unit. In this way, after step 204, the target gas shielded welding machine can adjust the set welding parameter range according to the environmental parameters, so as to set the welding parameter range matching the above environmental parameters. Specifically, the adjustment of the welding parameter range can be obtained based on actual construction experience combined with theoretical derivation, which is not specifically limited in this embodiment.

In another embodiment, the welding process parameters can be adjusted according to the actual welding results, and the corresponding processing can be as follows: detect the actual welding results of the target welding task, obtain the standard welding results of the welding process parameters; compare the actual welding results with the standard welding results The results are compared, and the welding process parameters of the target welding record are adjusted according to the comparison results.

In implementation, after the target welding task is completed, the gas shielded welding machine can detect the actual welding result of the target welding task, and at the same time obtain the standard welding result corresponding to the loaded welding process parameters, and then compare the actual welding result with the standard Compare welding results. Specifically, the detection of the actual welding results can be through image capture or ultrasonic induction, and the comparison process can include comparing the weld width, reinforcement, edge regularity and surface smoothness, as well as the size of the penetration depth and the presence or absence of pores. In this way, 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 results. It can be determined that the moving speed of the welding wire is too fast, and then the moving speed of the welding wire can be appropriately reduced.

In another embodiment, if there is no welding record corresponding to the task parameter in the current gas shielded welding machine, it can be searched in the welding records stored by similar gas shielded welding machines, and the corresponding processing can be as follows: if locally If there is no target welding record corresponding to the task parameters in the pre-stored historical welding records of the target gas shielded welding machine, a similar gas shielded welding machine is determined according to the equipment attribute information of the target gas shielded welding machine; obtained from the management center The historical welding records of similar gas shielded welding machines, and in the historical welding records of similar gas shielded welding machines, obtain the target welding records corresponding to the task parameters.

In implementation, after the target gas shielded welding machine obtains the task parameters of the target welding task, it can first search for the target welding record corresponding to the task parameters in the historical welding records of the target gas shielded welding machine stored locally. If it is not found, the target gas shielded welding machine can first determine the similar gas shielded welding machine whose model, factory batch, and service life are similar to the target gas shielded welding machine according to the attribute information of the target gas shielded welding machine. Welder. Furthermore, the target gas shielded welding machine can obtain the historical welding record of the similar gas shielded welding machine from the management center, and obtain the target welding record corresponding to the task parameters in the historical welding records of the similar gas shielded welding machine. Here, there can be multiple similar gas shielded welding machines, which can be divided into multiple levels according to the degree of similarity. When obtaining welding records, similar gas shielded welding machines can be selected step by step according to the degree of similarity. Specifically, one or more similar gas shielded welding machines with the highest degree of similarity (which can be referred to as first-level similar welding machines) can be selected first, and in the historical welding records of the first-level similar welding machines, the corresponding task parameters can be found. Target weld record. If it is still not found, you can further search for task parameters in one or more similar gas shielded welding machines with the second highest similarity (that is, second-level similar welding machines) and in the historical welding records of second-level similar welding machines The corresponding target welding record, and so on.

In another embodiment, the executive body of the above steps 201-204 may be the management center of the gas shielded welding machine. As shown in Figure 3, the management center can manage multiple gas shielded welding machines at the same time, and store Historical welding records of Taiwan gas shielded welding machine. The management center can receive the information content input by the user, and perform 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 is based on the above The data results in adjustments to the welding process. Of course, for step 205, since immediate feedback is required during the welding process, step 205 can be performed by a gas shielded welding machine to adjust the welding process.

Using the intelligent welding method based on the gas shielded welding machine disclosed in this application, when using the gas shielded welding machine for welding, the matching welding process parameters can be recommended to the construction personnel according to the task parameters of the welding task, so that the gas shielded welding The welding machine makes auxiliary adjustments to the welding process according to the welding process parameters, and can adjust the auxiliary level of equipment according to the actual situation of the construction personnel. In this way, selecting the established welding process parameters for the welding task, and the gas shielded welding machine assists welding based on the welding process parameters can greatly reduce the poor welding quality caused by the lack of personal skills and experience of the construction personnel, so that it can be obtained from Improve welding quality as a whole.
