<p>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.</p> |
