ENERGY BEAM BRAZING OR WELDING OF COMPONENTS

摘要

In a first stage process to assemble automotive body panels and join by soldering or welding on an assembly line, the two components are presented for assembly. The components form a narrow channel in which solder metal or welding wire is molten by a laser beam, forming a first seam line. In a second stage further solder or solder wire is presented and molten into the channel over the first solder or weld (11) layer. The soldering metal or weld wire employed in each stage has a melting point close to that of the other, e.g. copper or aluminum alloy.
