Abstract
Weldability of aluminumu alloy sheets for lap joints are researched. Joining Processes are friction stir welding and resistance spot welding.
In the friction stir welding, base metals are used Al-Mg and Al-Cu alloys. We are clarified the process parameters fot same kind joint and dissimilara joint.
In resistance spot welding, base metals are Al-Mg and Al-Mg-Si alloys. As a result, weldability are evaluated.
