摘要

A narrow band (1) of high-speed steel is welded to a wider band (2) of elastically flexible steel whilst using a cooled endless support belt (4) to press the narrow band against the wide band, the support belt being wider than the narrow band and travelling at the same speed as the welded strip. The contact region between the support belt and narrow band includes the welding spot and the subsequent stretch where the welded material hardens.
