Abstract
A method is provided for adjusting the thickness of the welding bead of two bands obtained by butt welding by means of a laser beam without using filler material. The bands are clamped in jaws, both cut edges being spaced apart by a reference distance. Then the mobile jaw is moved along a travel. Said travel differs from said reference distance by an offset calculated in relation to the thickness of the bands, and while taking into account the degree of accuracy of the positioning and of the cut of said edges. The offset is counted as positive or negative, in order to obtain a final welding position such that it exists, between the edges, an actual allowance, positive or negative, adapted to the thickness of the bands.
