A method for the production of a corrosion-resistant laser weld joint between two structural components and arrangement of two welded components

摘要

The present invention describes a process for the generation of a laser weld joint between two structural components (10, 20), comprising the steps of: providing a first component (10), which in the region of the compound to be a pad (11) of a first metal, whereby at least the terminal pad (11) of the first component (10) with a metal layer (14) is provided from a second metal. Providing a second component (20) with a body (21) from a third metal, in the region of the compound to be a welding aid (22) consists of a fourth metal, with a terminal pad (23) is applied. Provision of a corrosion-resistant layer of solder (30) on the flange face of the first and / or second component (10, 20), having a melting temperature which is smaller than the one in a welding zone of the components to be welded to one another (10, 20) occurring temperature. Flat contacting of the first and second component (10, 20) in the region of the connection surfaces. Carrying out the laser welding joint with melting of the solder of the solder layer (30), the resulting gaps as a result of the welding between the first and fourth metal and the welding zone (40) fills.
