LASER WELDING PROCESS FOR WELDING METAL COMPONENTS, PRODUCING A PLURALITY OF PROJECTIONS BY MEANS OF A LASER AT THE INTERFACE BETWEEN THE COMPONENTS

摘要

Such a process comprises the following steps: an upper metal component (1) is positioned on a lower metal component (2), superposing them at least in a welding zone; a plurality of projections (5) is produced on the lower face (6) of the upper metal component (1) facing the lower metal component (2) by means of a laser pulse applied at discrete points on said upper metal component (1), said projections (5) being spaced apart and spacing the upper metal component (1) away from the lower metal component (2); the two metal components (1, 2) are welded together in the welding zone by means of the laser beam.
