Mechanical Stir Lap Welding of Ferrous and Nickel Coated Steel: The Significance of the Ferrous Coat

The ferrous deuteroporphyrin cast Fe alloy and nickel-coated steel were lap welded successfully using the mechanical stir welding process. It was able to weld junctions with full strength and fracture on the base metal side of nickel-coated steel during the welding process, but ferrous alloy and nickel steel could not be welded together. It was proposed that the joining technique and function of the Ni coating be used in the friction stir lap welding of Ni-coated steel and aluminum alloy. The Ni coating improved both the weldability of iron and steel, resulting in the production of a Fe-Ni eutectic structure with a low melting point at the interface of the two materials. It is possible to successfully fuse steel and ferrous metals together.
