What is Aluminum Welding?by Julissa G. Content generator
Aluminum and aluminum alloys play a pivotal role in the various materials used in modern engineering technology. Its world annual output ranks second only to steel, and ranks first among non-ferrous metals. Aluminum alloys were first introduced in the aviation industry, but in recent years, in addition to the aviation industry, aluminum and aluminum alloys have also been widely used in automobiles, ships, bridges, machinery manufacturing, electricians, chemical industries and cryogenic plants to manufacture various components, fuel tanks, corrosion resistant containers and wires. At present, the most widely used aluminum alloy welded structure is rust-proof aluminum alloy, namely aluminum-magnesium alloy and aluminum-manganese alloy.
Aluminum welding refers to the welding process of aluminum alloy materials. The aluminum alloy is high in strength and light in weight. And its main welding processes are manual MIG welding (molten inert gas shielded welding) and automatic MIG welding. Aluminum welding generally requires base metal, welding wire, shielding gas and welding equipment.
Aluminum alloy welding method
1 tungsten argon arc welding
Tungsten argon arc welding is mainly used for aluminum alloys, which is a good welding method. However, tungsten argon arc welding equipment is complicated and is not suitable for operation under open air conditions.
2 resistance spot welding and seam welding
This welding method can be used to weld aluminum alloy sheets with a thickness of less than 5 mm. However, the equipment used in welding is complicated, and the welding current is large and the productivity is high, which is suitable for the mass production of parts and components.
3 pulse argon arc welding
Pulsed argon arc welding can improve the stability during welding and can adjust parameters to control arc power and weld formation. The weldment has small deformation and small heat-affected zone, and is especially suitable for the welding of thin plates, all-position welding and forging aluminum, hard aluminum and super-hard aluminum with high heat sensitivity.
