Characterization of EM welds

The objective of this present study is to characterization of EM welds; Electromagnetic welding is a solid state welding process, which produces a weld between two mating surfaces at high velocity of impact. In this report the metallurgical characterization of electromagnetic welds carried to find the presence of wave at the weld interfaces by using optical microscope and scanning electron microscopic results. Metallographic and micro hardness results of the welded specimens for the welding processes and Numerical analysis of impact welding are also presented here. Studies have revealed that critical velocity of impact is an important parameter for creating waves at the weld interface.
