A method for welding together two bodies, for instance pipes or plates, which are placed mutually in line against each other while leaving clear a weld groove, wherein the weld groove is filled with more than one welding layer by means of a welding torch moved in longitudinal direction of the weld groove, and wherein two welding layers are laid in one welding pass by means of two welding torches placed successively at a predetermined fixed distance in the longitudinal direction of the weld groove, so that a time-saving is achieved in the welding process. The invention also relates to a device for welding together two bodies, which device comprises two welding torches lying successively in the longitudinal direction of the weld groove.
L'invention concerne un procédé pour souder deux corps tel que des tuyaux ou des plaques, qui sont placés en ligne l'un contre l'autre avec une rainure de soudage au milieu. La rainure de soudage est remplie de plusieurs couches de soudage au moyen d'un chalumeau soudeur déplacé le long de la rainure de soudage, les deux couches de soudage étant déposées en une passe de rechargement au moyen de deux chalumeaux soudeurs placés l'un après l'autre à une distance fixe dans le sens de la longueur de la rainure de soudage; ainsi, on réalise une économie de temps pendant le soudage. L'invention concerne aussi un dispositif destiné à souder deux corps, le dispositif comprenant deux chalumeaux soudeurs placés l'un après l'autre le long de la rainure de soudage.
