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.

Abstract: The invention concerns a method for adjusting the thickness of the welding bead of two bands (M1, M2) obtained by butt welding by means of a laser beam without using filler material. The bands are clamped in jaws (S1, S2), both cut edges (10, 20) being spaced apart by a reference distance (D′). Then the mobile jaw is moved along a travel (C). Said travel (C) differs from said reference distance (D′) by a preset play 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 (10, 20). The preset play is counted as positive or negative, in order to obtain a final welding position such that it exists, between the edges (10, 20), an actual allowance, positive or negative, adapted to the thickness of the bends.

Abstract: The subject of the present invention is a method of spot resistance welding at least two metal pieces (1, 2). The method consists in pressing the pieces (1, 2) between two electrodes (3, 4), in determining the overall resistance between the electrodes (3, 4), and the contact resistances of each electrode (3, 4) with the piece (1, 2) with which it is in contact, in calculating the contact resistance between the said pieces by the difference between the overall resistance and the sum of the resistances of each piece and of the piece-electrode contact resistances, in determining the actual intensity of the electric welding current, and in adjusting the various welding parameters for the said pieces (1, 2) in order to maintain a constant optimal intensity of the electric welding current.The subject of the present invention is also a welding electrode for implementing the method.
