Abstract
A method for laser-light welding of a metallic base layer to a thin, metallic covering lying thereon, whereby the covering which is highly reflective for the laser light is covered with a metal skin which is less highly reflective for the laser light, namely with a metal skin which noticeably absorbs the laser light. In case both the covering as well as the base layer are wettable with solder metal, the covering highly reflective for the laser light is first covered with a metal skin composed of a solder metal, whereupon said covering is welded to the base layer by means of the laser light.
