IMPROVED FILLER WIRE FOR ALUMINIUM ALLOYS AND METHOD OF WELDING

摘要

A weld filler wire chemistry has been developed for fusion welding 2195 aluminum-lithium. Tile filler wire chemistry is an aluminum-copper based all oy containing high additions of titanium and zirconium. The additions of titani um and zirconium reduces the crack susceptibility of aluminum alloy welds while producing good weld mechanical properties. The addition of silver further improves the weld properties of the weld filler wire. The reduced weld crack susceptibility enhances the repair weldability, including when planishing is required.
