ABSTRACT:
A method for laser welding at least two metal parts, wherein the parts are welded along a weld area, includes simultaneously applying a continuous laser beam and a pulsed laser beam onto the weld area. The action of the pulsed laser is added to that of the continuous laser; with the continuous laser, it is possible to establish a stable molten bath in the weld area, the pulsed laser by its large peak energy, facilitating penetration of the energy and therefore of the molten bath, which allows deeper welding. A device for implementing the method is also disclosed.
