Arc joining of aluminum alloy to stainless steel with flux-cored Zn-based filler metal

Aluminum alloy was arc welded to stainless steel with a flux-cored Zn-based filler wire. Annealing enhanced the tensile strength of the joints, and fracture occurred through the aluminum base metal during testing. The weld consisted of a ZnO-enhanced Zn–Al cermet, and Fe–Al–Zn intermetallic compound...

Zusammenfassung:	Aluminum alloy was arc welded to stainless steel with a flux-cored Zn-based filler wire. Annealing enhanced the tensile strength of the joints, and fracture occurred through the aluminum base metal during testing. The weld consisted of a ZnO-enhanced Zn–Al cermet, and Fe–Al–Zn intermetallic compounds were detected within the interfacial layer.
