Abstract Invar alloy is widely used in the field of aeronautical composite die manufacturing because it has a very low coefficient of thermal expansion, which is like that of composite material. The laser-MIG (Metal-Inert Gas) hybrid welding was developed to join 10 mm thick Invar alloy plates using Invar M93 filling wire. High speed camera equipment was used to observe plasma dynamic processes. Three-dimensional finite element models of laser-MIG hybrid welding process were established to solve the flow field of the molten pool by two leading modes. Elaborated on the flow behavior of the molten pool More >
