Abstract

Metallic workpieces are drawn by applying traction while simultaneously locally heating to a temp. between an upper and lower limit. Heating and traction are such that the workpiece is locally stretched at a rate between an upper and lower limit. The position of the heated zone is maintained along its lengths to provide the required shape and elongation. The workpiece may have circular hole/s bored in it before stretching, and torsional or flexural forces may be applied to it during stretching.
