METHOD FOR PERFORMING A MAGNETIC PULSE WELDING OPERATION TO SECURE FIRST AND SECOND METALLIC COMPONENTS WITH A PREHEATING STEP FOR SOFTENING A FIRST PART OF THE FIRST MEMBER

摘要

A method of performing magnetic pulse welding operation to secure first and second metallic components (10, 20) together involves initially increasing the temperature of a first portion (11) 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 (11). Then, the first portion (11) of the first metallic component (10) is disposed in an axially overlapping manner relative to a portion of the second metallic component (20) with a space therebetween. An inductor (40) is provided relative to the axially overlapping portions of the first and second metallic components (10, 20). The inductor (40) is energized to deform the first portion (11) of the first metallic component (10) into engagement with the portion of the second metallic component (20) so as to secure the first and second metallic components (10, 20) together.
