Abstract
Welding of two or more steel sheets, at least one of which has a protective layer of a material with a low vaporization temperature, is carried out by directing a laser beam on two overlapped flanges of the sheets, which are clamped in position during welding by means of clamping devices. These clamping devices are able to hold the flanges to be welded in a slightly spaced apart position from each other, so as to create a gap, which does not jeopardize the possibility of carrying out the welding while enabling evacuation of the vapors of the protective material, which are generated during welding.
