A method of forming a laser weld along a discontinuous welding line by means of a welding device comprising means for emitting continuous laser radiation, an optical head (32) for focusing a laser beam from the emission means onto the parts to be welded, and means for moving the optical head (32) relative to the parts (14,16) to be welded along a predetermined working path corresponding to the welding line. The method includes the step of providing a screen (34) which is fixed relative to the parts to be welded (14,16) and extends along the welding line between the optical head (32) and the parts (14,16) to be welded. The screen (34) has a plurality of holes (36) arranged in correspondence with portions of the welding line in which the parts (14,16) are to be welded. <IMAGE> |
