Three Common Solutions for Aluminum Alloy Welding
Aluminum alloy is widely used in industrial products because it has good physical properties, almost all kinds of welding methods can be used to weld aluminum and aluminum alloy, but aluminum and aluminum alloy have different adaptability to various welding methods, and various welding methods have their own applications.
Due to improper selection of welding methods and welding process parameters, aluminum alloy parts m ay be welded resu l ti ng in serious deformation W eld porosity, slag entrapment, a nd lac k o f welding penetration c an al so lea d t o weld metal cracks or loose material, whic h c an seriously affect product quality and performance. Today , Heron introduces to you the industry's three common aluminum alloy welding so luti on s: tungsten arc welding, resistance spot and seam welding, and pulse argon arc welding.
1 Tungsten arc welding
Tungsten arc welding is mainly used for aluminum alloys na is a good welding pr ocess . How ever , tungsten arc welding equipment is more complex and is not suitable for operation in an open-air environment.
2. Resistance spot and seam welding
This welding pr ocess can be used to weld thin aluminum alloy plates with a thickness of less than 5mm. However, the equipment used during welding is more complex, requ irin g a large welding current na res ultin g i n high productivity I t is especially suitable for mass production of parts and components.
3. Pulse argon arc welding
