Arc welding

TIGstainless steel

Argon can effectively isolate air, is insoluble in metal and does not react with metal. During welding, the arc can also automatically remove the oxide film on the surface of the molten pool. Advantage Of Metal Stamping 1》 argon tungsten arc welding: ① Argon can effectively isolate air, is insoluble in metal and does not react with metal. During welding, the arc can also automatically remove the oxide film on the surface of the molten pool. Therefore, it can successfully weld non-ferrous metals, stainless steel and various alloys that are easy to oxidize, nitride and chemically active. ② Tungsten electrode arc is stable, and dozens of it can still burn stably under a small welding current (less than 10a), which is especially suitable for the welding of thin plates and ultra-thin materials. ③ The heat source and filler wire can be controlled separately, so the heat input is easy to adjust, and welding at various positions can be carried out. It is also an ideal method to realize single-sided welding and double-sided forming. ④ Since the droplet of filler wire does not pass through the arc, no spatter will occur, and the weld formation is beautiful. 2》 MIG welding: ① Inert gases have little chemical interaction with any metal. ② There is no coating layer on the surface of the welding wire, and the welding current can be increased. Therefore, the penetration of the base metal is large, the welding wire melting speed is fast, and the deposition rate is high. Compared with TIG (tungsten insert gas arc welding) welding, its production efficiency is high. ③ Droplet transfer mainly adopts jet transfer. Short circuit transition is only used in thin plate welding,
