Title: LASER WELDING METHOD AS WELL AS CLAMPING ARRANGEMENT
Abstract:
The invention relates to a laser welding method, in which two workpieces (16, 18, 20) to be welded together are positioned relative to each other in a clamping device (10) that has an upper clamping element (12) with through-holes for laser radiation and delimits an interior space, and gas is conducted in said interior space in a targeted manner. The gas is conducted by a gas conducting device (24) that extends at a distance from the workpieces (16, 18, 20) and along a boundary (26) of the clamping device (10).
