Automatic laser soldering of workpieces

摘要

Workpieces (20) are laser-soldered by a method in which sections of solder (14.1) are cut up into one or several solder wires (14) by means of a cutter unit (11), the wires falling into openings (13.1) of workpiece holding-down clamps (13). The positions of the openings coincide with those locations on the workpieces which are to be soldered. The assembly is then fed to a laser soldering unit (10) for soldering. Pref. soldering takes place under protective gas, partic. N2 enriched with formic acid, and no flux is used.
