Weld-on element for friction welding to workpiece or component is partly in form of friction ring of specified dimension ratios

摘要

The weld-on element (1) is made at one end with a specific shape and cross section in the form of a friction ring (2). The external diameter (da) and the internal diameter (di) of the friction ring to boring depth (si) of the ring are in a specified ratio. The friction surface widths (b) of the friction ring are between 0.5 mm and 8 mm.
