Microstructure and mechanical properties of nano-treated 7075 aluminum alloy joint fabricated by laser-MIG hybrid welding

Hot cracking and joint softening are the two main factors restricting the achievement of high-performance fusion welding joints of 7075 aluminum alloy. This paper utilized low heat input laser-melt inert gas welding (MIG) hybrid welding to butt weld 7075 aluminum alloy. The crack-free joint was obta...
