Description

technical field [0001] The invention relates to the field of welding machines, in particular to an automatic argon arc welding machine. Background technique [0002] Argon arc welding technology is based on the principle of ordinary arc welding, using argon to protect the metal welding material, so that the tungsten tip, arc and molten pool and the high-temperature metal adjacent to the heat-affected zone are not in contact with the air, preventing the welding material from collapsing. Oxidation is a welding technique that melts the welding material into a liquid molten pool through the welding current, so that the metal to be welded can achieve metallurgical bonding. Due to the continuous supply of inert gas argon in high temperature welding, it can weld stainless steel, low carbon steel, etc., as well as some refractory metals and easily oxidized metals, such as magnesium, titanium, molybdenum, zirconium, aluminum, etc. and their alloys. [0003] The arc of argon arc weld...

AI Technical Summary

Problems solved by technology

[0003] The arc of argon arc welding is stable, the heat is concentrated, the stress and deformation are small, the electrode loss is small, and there is no solvent and coating layer during welding. However, the degree of mechanization and automation of argon arc welding machines on the market is low, the welding quality cannot be guaranteed, and the operation is not convenient enough.
