Abstract
There is described a method for submerged-arc narrow-gap welding, in which the wire electrode is set in oscillating motion in the gap in order to produce a first bead, the arc moving backwards and forwards between one of the workpiece edges and a middle section of the gap so that the first bead does not extend from the first to the second workpiece edge.

A method for submerged arc narrow gap welding, comprising:
- providing a welding device which can be traversed within a gap between a first and a second workpiece sidewall and has a movable wire electrode for selectively positioning an arc;
- striking the arc at the end of the wire electrode;
- providing an oscillating movement of the wire electrode inside the gap to produce a bead, wherein the arc moves back and forth between one of the workpiece sidewalls and a central region of the gap, wherein the bead does not extend from the first to the second workpiece sidewall.
