The invention concerns a method for overlapping welding of two coated metal sheets (1, 2) with a beam of high energy density (11), characterized in that it consists in splitting the beam (11) into a first sub-beam (12) passing through both coated metal sheets (1, 2) and forming in said zone a first molten metal bath (18) and into a non-through second sub-beam (13) forming a second molten metal bath (19) whereof the depth is less than the thickness of the upper coated metal sheet (1) and overlapping at least part of the first molten metal bath (18) for promoting evacuation of vapour from the coating material and directing on the second molten metal bath (19) a neutral gas jet with high ejection speed to form at the surface of the second molten metal bath a sink (22).
L'invention concerne un procédé de soudage par recouvrement ô l'aide d'un faisceau ô haute densité d'énergie (11) de deux tôles (1, 2) revêtues, caractérisé en ce que l'on sépare le faisceau (11) en un premier sous faisceau (12) traversant les deux tôles (1, 2) revêtues et formant dans cette zone un premier bain de métal fondu (18) et en un second sous faisceau (13) non traversant et formant un second bain de métal fondu (19) dont la profondeur est inférieure ô l'épaisseur de la tôle revêtue supérieure (1) et chevauchant au moins une partie du premier bain de métal fondu (18) pour favoriser l'évacuation de la vapeur du matériau de revêtement et on dirige sur le second bain de métal fondu (19) un jet de gaz neutre ô haute vitesse d'éjection pour former ô la surface du second bain de métal fondu une cuvette (22).
