摘要: Articles are often formed from a tubular workpiece in a process which does not usefully shape the ends of the tube. In an embodiment of the invention, tube ends may be mechanically reduced in cross section and then expanded against a secondary forming surface(s) using an electromagnetic force to obtain desired shapes for the tube ends and minimize scrapping of workpiece material.
