Method and apparatus for performing a magnetic pulse welding operation

Abstract

A pair of metallic components are co-axially aligned prior to full energization of the magnetic pulse welding inductor to provide for improved control of the magnetic pulse welding process. To accomplish this, either or both of the components are supported in a floating manner. An electromagnetic coil is then energized so as to generate a magnetic field of relatively small intensity within or about one of the components. This relatively small intensity magnetic field exerts a relatively small force on the two components, causing them to move to a co-axially aligned position relative to one another and to the coil. Then, while the components are co-axially aligned, they are subjected to a magnetic field of relatively large intensity for the purpose of permanently joining such components together. This relatively large intensity magnetic field exerts a large pressure on one of the two components, causing it to deform toward the other of the two components at a high velocity. The high velocity impact of these two components, as well as the large pressures exerted thereon, caused the two components to become permanently joined together.
