摘要：
Feasibility of electromagnetic welding of flat sheets is ascertained by comparing the minimum impact velocities determined by using software ANSYS/EMAG and ABAQUS with the required minimum velocity obtained from analytical considerations. Magnetic forces acting on the sheets are computed from ANSYS/EMAG simulations. The velocity of impact and the pressure profile acting on the sheets are found from ABAQUS simulations. Acriterion for weld formation is subsequently arrived at based on the simulations, which is further validated using experimental results. The reasons for no-weld zone in Al-to-Al EM weld and complete metal continuity (absence of no-weld zone) in Al-to-SS EM weld have been analyzed based on the numerical and experimental results.
