Improved filler wire for aluminum 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 alloy containing high additions of titanium and zirconium. The additions of titanium 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. <IMAGE>
