Method for joining dissimilar materials and products manufactured using the same

Abstract

The present invention relates to a method for joining dissimilar materials and a manufactured product using the same, and more specifically, to a method for joining dissimilar materials and a manufactured product using the same, comprising: a target material preparation step of preparing a non-metallic lightweight material and an ultra-high strength steel to be joined by a Friction Element Welding (FEW) method; and a target material joining step of joining the non-metallic lightweight material and the ultra-high strength steel while controlling at least one of the pressure and rotational speed of a FEW rivet based on the thickness of the non-metallic lightweight material, the type of the ultra-high strength steel, and at least one of the requirements for Tensile Shear Strength (TSS) and Cross Tensile Strength (CTS).
