How To Weld Aluminum Alloy?
Can be welded, welding method:
1. Argon tungsten arc welding
Argon TUNGSTEN ARC welding is mainly used in aluminum alloy, is a good welding method, but the tungsten argon arc welding equipment is more complex, not suitable for open air conditions.
2, resistance spot welding, seam welding
This welding method can be used to weld aluminum alloy sheet with thickness up to 5mm. But the equipment used in welding is more complex, welding current is large, high productivity, especially suitable for mass production of zero, parts.
3. Pulsed argon arc welding
Pulse argon arc welding can improve the stability of welding process and adjust parameters to control arc power and weld forming. The weldment has small deformation and small heat affected zone. It is especially suitable for the welding of sheet metal, all-position welding and the forging aluminum, hard aluminum and super hard aluminum with strong heat sensitivity.
4. Friction stir welding
Friction stir welding first and mainly in aluminum alloy, magnesium alloy and other light metal structure field has been more and more widely used, the biggest characteristic of this method is that the welding temperature is lower than the melting point of the material, can avoid by fusion welding caused by cracks, pores and other defects.
