1. Argon tungsten arc welding

The argon tungsten arc welding method is mainly used for aluminum alloys and is a better welding method, but the argon tungsten arc welding equipment is more complicated and is not suitable for operation in the open air. -- Aluminum Alloy Welding Wire Suppliers

2. Resistance spot welding and seam welding

This welding method can be used to weld aluminum alloy sheets with a thickness below 5mm. However, the equipment used in welding is relatively complicated, the welding current is large, and the productivity is high, which is especially suitable for mass-produced parts and components.

3. Pulse argon arc welding

Pulsed argon arc welding can improve the stability of the welding process very well. The parameters can be adjusted to control the arc power and weld shape. The weldment has small deformation and small heat-affected zone, which is especially suitable for thin plate, all-position welding and other occasions, as well as welding of forged aluminum, duralumin, super duralumin, etc. that are highly sensitive to heat.

4. Friction stir welding

Friction stir welding is firstly and mainly used in the field of light metal structures such as aluminum alloys and magnesium alloys. The biggest feature of this method is that the welding temperature is lower than the melting point of the material, which can avoid cracks and pores caused by fusion welding. defect.
