Abstract (en)
[origin: CA2624407A1] The present invention discloses a method for submerged-arc narrow-gap welding, in which the wire electrode (30) is set in oscillating motion in the gap (10) in order to produce a first bead (50), the arc (40) moving backwards and forwards between one of the workpiece edges (20a, 20b) and a middle section (12) of the gap (10) so that the first bead (50) does not extend from the first (20a) to the second workpiece edge (20b).
