This welding method can be used to weld thin aluminum alloy plates with a thickness of less than 5mm. However, the argon tungsten arc welding equipment is more complicated and is not suitable for operation in open air. The GTAW welding method is mainly used for aluminum alloys and is a better welding method. The main chemical composition of base metal and welding wire: The main welding process is manual MIG welding (Melting Inert Gas Shielded Welding) and automatic MIG welding, the base material, welding wire, shielding gas, and welding equipment. Aluminum alloy has high strength and light weight. At present, the most widely used aluminum alloy welding structure is rust-proof aluminum alloy, namely aluminum-magnesium alloy and aluminum-manganese alloy.Īluminum alloy welding refers to the welding process of aluminum alloy materials. Alloy to manufacture various parts, fuel tanks, corrosion-resistant containers and wires. If aluminum alloy first emerged in the aviation industry, in recent decades, in addition to the aviation industry, aluminum and aluminum have been widely used in aerospace, automobiles, ships, bridges, machinery manufacturing, electrical engineering, chemical industries, and cryogenic devices. Its annual output in the world is second only to steel, and it ranks first in non-ferrous metals. The main welding processes are manual TIG welding (non-melting inert gas shielded welding), automatic TIG welding and MIG welding (melting polar inert gas shielded welding), the base material, welding wire, shielding gas, and welding equipment.Īluminum and aluminum alloy occupies a pivotal position in the various materials used in modern engineering technology. Aluminum alloy welding refers to the welding process of aluminum alloy materials.
