Abstract
A method of continuous welding of a series of tubes to a tube sheet, in which the torch current is decreased to produce partial fading of the arc after completion of the first welding bead, and the torch is then moved to a starting position on a second contour to be welded. A stationary preheat is then effected, and a second weld bead is made by following the second contour to be welded. The process continues until the last bead has been made, whereupon the arc is switched off.
