THE METHOD OF WELDING WORKPIECES ALONG A SEAM BY MEANS OF A BEAM OF CHARGE CARRIERS COMPRISING THE STEPS OF FOCUSING THE BEAM ON A FIRST POINT ALONG SAID SEAM, ADJUSTING THE INTENSITY OF THE BEAM SO THAT IT WILL PENETRATE ONLY PARTIALLY INTO THE SEAM, WELDING THE WORKPIECES TOGETHER OVER ONLY A PORTION OF THE SEAM DEPTH AND PRODUCING A PROTRUDING WELD BEAD ON THE UPPER SURFACE OF THE SEAM DURING SAID PENETRATION, THEN DIRECTING THE BEAM ON A SECOND POINT CLOSELY ADJACENT SAID FIRST POINT AND ALONG SAID SEAM TO PRODUCE A SECOND PROTRUDING WELD AND THEN DIRECTING THE BEAM WITH SUBSTANTIALLY THE SAME INTENSITY ON SAID FIRST PROTRUDING WELD BEAD AT SAID FIRST POINT TO COMPLETELY WELD THE WORKPIECES TO THE FULL SEAM DEPTH, FORMING A WELD BEAD PROTRUDING ON BOTH SIDES OF THE SEAM.
