摘要：The 7N01-T5 alloy (AT5) and 7N01-T4 alloy (AT4) were butt welded by metal inert gas (MIG) welding with ER5356 filler wire, and the mechanical properties and corrosion resistance of welded joint were investigated. The mechanical properties of welded joint are inferior to those of base metals (BMs). In the welded joint, the difference in composition of Zn, Cu and the amount of precipitates between AT5 side and AT4 side induces the variance of corrosion potential, resulting in the appearance of galvanic corrosion, then the highest corrosion susceptibility occurred on the AT4 side of the region adjacent to the weld zone.
