[0062] The information sending module is used to send the welding environment control information, welding material control information, welding test warning information and welding test evaluation information to a preset receiving terminal after the above information is generated;
[0063] Through the generated welding environment control information, it is possible to timely discover whether the welding test environment of the inverter welding machine is abnormal, and then make timely adjustments to ensure environmental stability and reduce the impact of environmental factors on the accuracy of welding test results. Through the generated welding material control information, it is possible to timely discover whether the overall quality of the welding materials being tested is normal, and then make timely adjustments to avoid the abnormal quality of welding materials affecting the referenceability of the welding test results of the inverter welding machine. Through the generated welding test warning information, the safety of the welding test can be guaranteed to avoid safety accidents during the welding test. Through the generated welding equipment abnormality information, it is possible to timely discover whether the inverter welding machine to be tested is abnormal, and make timely adjustments to avoid the abnormal inverter welding machine affecting the test progress and the accuracy of the test results. Through the welding test evaluation information, users can intuitively understand the welding effect of the inverter welding machine, and realize that on the basis of being able to more accurately obtain the test results of the inverter welding machine, the impact of external factors on the test results is further reduced, ensuring the safety of the test and the accuracy of the test results.
[0064] The specific processing process of the welding environment control information is as follows: extracting the collected welding test environment information of the inverter welding machine;
[0065] The welding test environment information of the inverter welding machine includes real-time environment temperature information, real-time environment humidity information, real-time environment dust concentration, real-time environment vibration force and real-time power supply fluctuation amplitude;
[0066] Then, the model information of the inverter welding machine is collected, and the model information of the inverter welding machine is imported into an Internet database, and the optimal operating environment temperature range, optimal operating humidity range, optimal environmental dust concentration value and optimal environmental vibration force value of the corresponding inverter welding machine model are retrieved from the Internet database;
[0067] When any of the following occurs: the real-time ambient temperature information is not within the optimal operating ambient temperature range, the real-time ambient humidity information is not within the optimal operating humidity range, the real-time ambient dust concentration is greater than the optimal ambient dust concentration value, the real-time ambient vibration force is greater than the optimal ambient vibration force value, and the real-time power supply fluctuation amplitude is greater than the preset value, the welding environment control information is generated;
[0068] The impact of the environment on the inverter welding machine is multifaceted, mainly including the following aspects:
[0069] Overheat protection: The inverter welding machine will be affected by the temperature of the surrounding welding. If the ambient temperature is too high or the welding machine works at high load for a long time, the internal temperature of the welding machine will rise, which may trigger the overheat protection circuit, thus interrupting the welding process or damaging the welding machine. To avoid this situation, ensure that the welding machine works within the appropriate temperature range and take necessary heat dissipation measures, such as adding ventilation or cooling equipment.
[0070] Component aging: High temperature will also accelerate the aging of the components inside the welding machine and shorten the service life of the welding machine. Therefore, when using the inverter welding machine, try to avoid placing it in a high temperature environment, and perform regular maintenance, check and replace aging components.
[0071] Degradation of electrical insulation performance: In a humid environment, the electrical insulation performance of the inverter welding machine may be reduced, thereby increasing the risk of leakage. This may lead to safety accidents such as circuit short circuit and spark. Therefore, when using the inverter welding machine in a humid environment, special attention should be paid to safety precautions, such as strengthening insulation treatment and using moisture-proof equipment.
[0072] Circuit instability: Moisture can also affect the stability of the welding machine, making the welding quality unguaranteed, because moisture can make the capacitors, relays and other parts of the welding machine damp, causing circuit instability or damage.
[0073] Dust and corrosive gases: These environmental factors can also have adverse effects on the inverter welding machine. Dust may block the heat dissipation holes of the welding machine, affecting the heat dissipation effect; while corrosive gases may corrode the metal parts and circuit components of the welding machine, causing damage to the equipment. Therefore, when using the inverter welding machine, try to avoid placing it in an environment with high concentrations of dust and corrosive gases.
[0074] Vibration and shock: Strong vibration and shock may also cause damage to the inverter welding machine. This may cause the internal components of the welding machine to loosen, fall off or be damaged, thus affecting the normal operation of the welding machine. Therefore, when using and transporting the inverter welding machine, try to avoid severe vibration and shock.
[0075] The environment has many effects on the inverter welding machine, including temperature, humidity, dust, corrosive gas, vibration and impact. In order to ensure the normal operation and service life of the inverter welding machine, attention should be paid to the influence of environmental factors during use and corresponding preventive measures should be taken. At the same time, it is also very important to regularly maintain the welding machine.
[0076] The specific process of obtaining welding material control information is as follows:
[0077] Extracting the collected welding test material information, the welding test material information includes welding material quantity, welding material image information and welding material weight information;

[0079] The number of welding materials is marked as i, the number of abnormal welding materials among the i welding materials is extracted and marked as z, and the ratio of z to i is calculated to obtain the overall evaluation parameter. When the overall evaluation parameter ratio is greater than the preset value, the welding material control information is generated. The specific content of the welding material control information is that there is a problem with the overall quality of the welding material, and it needs to be replaced as a whole.
[0080] The process of obtaining the monomer evaluation parameters is as follows:
[0081] Extract the welding material image information, perform welding material recognition processing on the welding material image information, and obtain the real-time welding material length, real-time welding material width and real-time welding material thickness;
[0082] The standard surface color information of the standard welding material is set, and the standard surface color information of the standard welding material is imported into the welding material image information to perform standard surface color recognition and obtain the real-time standard surface color area;
[0083] The standard length, standard width, standard thickness, standard color area and standard welding material weight of standard welding materials are also set;
[0084] Calculate the difference between the length of the real-time welding material and the standard length, and obtain the length evaluation parameter Ki; calculate the difference between the width of the real-time welding material and the standard width, and obtain the width evaluation parameter Ei; calculate the difference between the thickness of the real-time welding material and the standard thickness, and obtain the thickness evaluation parameter Ui;
[0085] The difference between the standard surface color area and the standard color area of the welding material is calculated to obtain the standard color evaluation parameter Gi; the difference between the weight information of the welding material and the standard welding material weight is calculated to obtain the weight evaluation parameter Wi;
[0086] The standard color evaluation parameter Gi can be used to understand whether there are impurities such as oil and oxide on the surface of the welding material. Impurities such as oil and oxide will affect the welding quality. The surface of the welding material should be clean and free of impurities such as oil and oxide to ensure good contact and current conduction during welding.
[0087] The length evaluation parameter Ki, the width evaluation parameter Ei, the thickness evaluation parameter Ui, the color evaluation parameter Gi and the weight evaluation parameter Wi constitute the monomer evaluation parameters of a single welding material;
[0088] The content of judging whether the welding material is abnormal is as follows: when any one of the length evaluation parameter Ki, width evaluation parameter Ei, thickness evaluation parameter Ui, color evaluation parameter Gi and weight evaluation parameter Wi in the single evaluation parameter is abnormal, it means that the welding material is abnormal;
[0089] If the length evaluation parameter Ki exceeds the preset range, it means that it is abnormal;
[0090] If the width evaluation parameter Ei exceeds the preset range, it means that it is abnormal;
[0091] If the thickness assessment parameter Ui exceeds the preset range, it means that it is abnormal;

The machine position safety protection range is within the rectangular range.
[0097] When the welding test is performed on multiple inverter welding machines at the same time, a safety range assessment is also required. When multiple welding equipment is tested at the same time, after the safety range of each inverter welding machine is marked, the closest distance between the edges of each safety range is collected. When the closest distance between the edges of the safety range is less than the preset value, a welding test warning message is generated. At this time, the specific content of the welding test warning message is that the distance between the inverter welding machines is too close, and the test position needs to be adjusted.

[0099] Calculate the difference between the inverter welding machine access current information and the preset standard current, and obtain the current difference;
[0100] Calculate the difference between the inverter welding machine access voltage and the preset standard voltage, and obtain the voltage difference;
[0101] When the current difference exceeds the preset range, the voltage difference exceeds the preset range, or the information of the connected power cable is abnormal, the welding equipment abnormal information is generated;
[0102] According to the type and thickness of the welding material, set the welding current and voltage reasonably to ensure the welding quality. Check whether the current and voltage regulation are accurate and reliable.
[0103] The process of determining whether the power cable information is abnormal is as follows: the power cable information includes the force magnitude of the power cable information and the number of turns of the power cable at an angle greater than a preset value. When the force magnitude of the power cable information is greater than a preset value or the number of turns of the power cable at an angle greater than a preset value is greater than a preset number, abnormal welding equipment information is generated.
[0104] Welding test assessment information includes level one assessment, level two assessment and level three assessment;
[0105] The specific process of obtaining welding test evaluation information is as follows: extracting the collected welding related information, which includes the defect quantity information and strength test data of the completed welding test;

[0107] When the defect quantity information is between a1 and a2, and the strength test data is greater than the preset value, a secondary assessment is generated;
[0108] When the defect quantity information is less than the preset value a1 and the strength test data is less than the preset value, a secondary evaluation is generated;
[0109] In addition to the above conditions, a third-level assessment is generated;
[0110] The first-level assessment means that the welding quality of the inverter electric welder is good, the second-level assessment means that the welding quality of the inverter electric welder is average, and the third-level assessment means that the welding quality of the inverter electric welder is poor.
[0111] The process of obtaining welding related information is as follows: After the welding test material is completed using the inverter electric welder, the ultrasonic flaw detection method and the radiographic flaw detection method are used to detect weld defects. The real-time defect number detected by the ultrasonic flaw detection method is marked as E1, and the real-time defect number detected by the radiographic flaw detection method is marked as E2. The average of E1 and E2 is calculated to obtain the defect number information;
[0112] After completing defect detection using ultrasonic and radiographic methods, a tensile strength test is performed to detect the maximum tensile force when the weld breaks, and the strength test number is obtained.
[0113] Ultrasonic flaw detection method: uses the propagation characteristics of ultrasonic waves in materials to detect internal defects in welds, including cracks, incomplete penetration, and slag inclusions.
