抄録

A study has been made of the weldability of Al-Zn-Mg alloys. The experiments were carried out on the aging characteristics, tensile properties and weld-crack susceptibility of MIG-spot welds.<BR>Tensile properties were evaluated by the tensile-shear and the cross-tension test, and weld-crack susceptibility was evaluated by the slit-type weld-cracking and the restrained weld-cracking tests.<BR>The tensile-shear strengths of MIG-spot welds made with 5356 filler and AIZnMgZr filler were 500 kg/spot and 600 kg/spot respectively in 60 days after welding. Cross-tension strength decreased with aging after welding, while tensile-shear strength increased.<BR>According to the restrained weld-cracking test, crack susceptibility of MIG-spot welds in AI-Zn-Mg alloy was almost equal to that of 5052 alloy. However, crack susceptibility of Al-Zn-Mg alloy containing small amount of zirconium was almost equal. to that of 5083 alloy.<BR>Weld-crack susceptibility of AlMg alloy (upper sheet)-AlZnMg alloy (lower sheet) combination showed the tendency of smaller susceptibility than AlZnMg-AlZnMg combination.
