Study of Wavy Interface in Electromagnetic Welds

Abstract:

Wavy interface is a characteristic of an impact weld. Electromagnetic pulse welding is a solid state welding process, which produces a weld between two mating surfaces at high velocity of impact. In this paper studies on metallurgical characterization of electromagnetic welds to find the presence or absence of wavy weld interface, by using optical microscope and scanning electron microscope, are reported. EM welds of Al to Al do not show wavy interface due the low energy of impact. EM welds of Al to Steel show wavy weld interface due to instability at the weld interface. Studies have revealed that discharge energy and critical velocity of impact are the important parameters for creating stronger electromagnetic welds and the wavy weld interface.
