Problems solved by technology

[0002] The welding process is an important mechanical processing method when mechanical products are formed, so the welding machine is an important mechanical processing equipment. In the existing welding machines, the operators determine the welding parameters according to their operating experience. , and then weld. After the product is welded and formed, the welding quality of the product is inspected. The welding parameters have a great influence on the welding quality. When welding the pressure vessel or nuclear power capacitor, the consistency of the welding parameters should be maintained. It plays a very important role in the welding quality of the container, so the device for monitoring welding parameters is an important detection device. In the existing welding process, there is no device for monitoring welding parameters. Personnel self-control, maybe in order to increase the welding speed, some operators may change the welding parameters, thus affecting the welding quality
