Welding method of aluminum alloy
1、Tungsten arc argon arc welding
Tungsten inert gas arc welding is mainly used for aluminum alloy. It is a better welding method. However, tungsten inert gas arc welding equipment is more complex, and it is not suitable for operation under open air condition.
2、Resistance spot welding, seam welding
This welding method can be used to weld aluminum alloy sheets under the thickness of less than 5mm. But the equipment used in welding is more complex, the welding current is big and the productivity is high. It is especially suitable for the parts of large mass production.
3、Pulsed argon arc welding
Pulsed argon arc welding can improve the stability of the welding process and can adjust the parameters to control the arc power and weld formation. The welding piece has small deformation and small heat affected zone. It is especially suitable for welding thin plates, all position welding, and heat sensitive aluminum forged, hard aluminum and super hard aluminum.
