Abstract
A rotary friction welding process is provided, including: providing a first axisymmetric workpiece having a first annular weld surface, and a second axisymmetric workpiece having a second annular weld surface; and rotationally welding the workpeices. On the longitudinal section through the aligned workpieces, each of the first and second annular weld surfaces is flanked by radially inner and outer side surfaces, the first weld surface and its side surfaces being shaped to thermally match the second weld surface and its side surfaces across a line of initial contact of the first and second weld surfaces such the heat flows from the weld at all the side surfaces are substantially equal.
