ABSTRACT OF THE DISCLOSURE: Method of making a great number of weld beads in the form of independent contours spaced apart by means of an auto- matic welding head comprising a torch and means for displacing the torch in several directions allowing the latter to follow each contour one after the other. The method is characterized by the fact that after striking of the arc and positioning of the torch on the first contour to be welded and then making of the first weld bead have been effected in a known way, the torch current is decreased to effect a partial fading out of the arc. A displacement of the torch is then effected as far as a starting position on a second contour to be welded, and a timed stationary preheat is effected at this point by control- ling the return to welding current. The second weld bead is made by following the second contour to be welded, the torch current is then decreased to obtain a further partial fading out of the arc, and a further displacement of the torch is effected as far as a starting point on a third contour to be welded. The third contour is then done and so on, transfer from one contour to the other and adjustment of welding para- meters is effected automatically until the last bead is made. The arc is then switched off.
