Experimental and numerical study on magnetic pulse welding to improving the life time of one-turn flat coil

Abstract

The objective of this investigation was to obtain an improved understanding of magnetic pulse welding processes and the mechanisms of electromagnetic forces applied to a one-turn flat coil. Results of simple numerical investigation and experiments show that the electromagnetic forces on the middle part of the coil can be canceled out by loading the welded workpieces on both sides of the coil and can prevent coil deformation and improve its lifetime.
