Problems solved by technology

[0002] In the existing welding equipment, there are many technologies such as explosive welding and vacuum welding. Among them, vacuum electron beam welding is the welding of materials in a vacuum environment. Electron beams can weld different metals and alloy materials, especially high refractory metals. Welding, and the welding precision is high, the efficiency of welding large and thick parts is higher, the welded joints are of high purity, the weld seam is pure, smooth, mirror-like, and free of oxidation and other defects; but at present, due to the long vacuuming time of large-scale vacuum electron beam welding, about It takes 10-15 minutes, and repeated vacuuming is required for each welding, which affects the production efficiency of the equipment, especially when welding small parts, it cannot be welded continuously, and the vacuuming time seriously affects production efficiency. At the same time, the welding stress cannot be eliminated, which affects the strength; in addition , in the existing welding process, there is a need to switch to argon arc welding equipment for alternate welding operations, resulting in a large amount of smoke during the welding process, which seriously affects the welding quality of the welded parts and the health of personnel
