摘要
The invention relates to a laser welding device for braze-welding a first sheet metal part to a second sheet metal part, comprising a frame (5) supporting a head (6) that emits a laser beam (7) and a nozzle (8) that supplies the welding wire, which are configured to produce a welding bead along a junction line between said first and second sheet metal parts. The frame (5) also supports a pressure-roller (10) configured to press one of the parts against the other, said pressure-roller (10) being positioned upstream of the laser beam (7) in the direction (F) in which the laser beam (7) moves along said junction line. The invention is characterised in that the frame (5) also supports a second pressure-roller (12), the position of which is offset in relation to that of the first pressure-roller (10) in the direction (F) in which the laser beam (7) moves.
