摘要

Method for welding bolts (1) to workpieces (30) comprises melting a mass of welding material (15) between them and moving them relative to each other to produce a bond. Melting of the welding material is carried out by setting up an arc between the bolt and workpiece. An independent claim is included for bolts for use in the method which have a flange (10) on the end to be welded.
