Critical Analysis on Magnetic Pulse Welding of Similar and Dissimilar Metals
Abstract
Magnetic pulse welding is a high-speed welding process that uses an electromagnetic force to accelerate one metal to other resulting in a solid-state weld without any external heat source. Since the melting of materials is avoided, magnetic pulse welding is an efficient method for welding dissimilar metals. Discharge current of 220 kA and 140 kA from a 40 kJ, and 17 kJ capacitor bank is flowing in the disk coil that produces required pressure to weld metals at 20 kV and 13 kV are analysed. Welding of stainless steel tube (outer workpiece) of 6.5 mm diameter and varying thickness of (0.1 mm–1 mm) to stainless steel rod (inner workpiece) of 5.5 mm diameter and welding of copper tube (outer) of 6.5 mm diameter to steel rod (inner) of 5.5 mm diameter is comparatively demonstrated. MATLAB programming is done for calculation of various parameters at a high voltage power source. Pressure and force required to weld similar and dissimilar metals at different thicknesses of the outer workpiece are presented in the paper.
