ABSTRACT:
Filler metal for welding AlZnMg type alloys raises the resistance to stress corrosion without increasing the susceptibility to exfoliation corrosion. The composition of the filler metal includes a copper addition which suppresses weld boundary corrosion while additions of manganese, titanium, chromium and zirconium inhibit weld cracking. High weld strengths are attained using the said filler metal.
