Abstract
A method and apparatus for welding together two pipes or plates. The bodies to be welded are placed mutually in line against each other while leaving clear a weld groove. The weld groove is filled with more than one welding layer by a welding torch moved in a longitudinal direction of the weld groove, and wherein two welding layers are laid in one welding pass by 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.
