US 2006/0131300 A1 · Method for performing a magnetic pulse welding operation

Abstract

A method of performing magnetic pulse welding operation to secure first and second metallic components together involves initially increasing the temperature of a first portion of the first metallic component to soften same without substantially increasing the temperature of and softening a second portion of the first metallic component adjacent to the first portion. Then, the first portion of the first metallic component is disposed in an axially overlapping manner relative to a portion of the second metallic component with a space therebetween. An inductor is provided relative to the axially overlapping portions of the first and second metallic components. The inductor is energized to deform the first portion of the first metallic component into engagement with the portion of the second metallic component so as to secure the first and second metallic components together.
