METHOD AND ARRANGEMENT FOR LASER WELDING

摘要

Laser welding is accomplished in a laser welding arrangement by positioning a plurality of workpieces to be joined next to one another so as to form an assembly having at least one interface between the workpieces, by simultaneously directing two laser beams from opposite sides of the assembly against effective welding regions of the workpieces that adjoin the interface and are substantially aligned with one another across the interface, and by effecting relative movement between the assembly and the two laser beams along the interface while maintaining the substantial alignment of the effective welding regions.
