What is Aluminum Welding?
by Julissa G. Content generatorAluminum 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.
