Abstract

PURPOSE: To weld weldments from both sides and make the welding of long size materials easy by moving the weldments between the welding arcs which oppose to each other with a mutual deviation.
CONSTITUTION: Long size weldments 2 are positioned perpendicularly and welding arc generating parts 1a, 1b are fixed horizontally to each of the front side 2a and back side 2b of the weldments 2. At this time, the interpole distance L of the torches A, B of the arc generating parts 1a, 1b is spaced to the extent that the arcs do not interfere with each other. Next, while the weldments 2 are being moved in an arrow direction, single-pass welding is carried out by the two welding arc generating parts 1a, 1b from both sides without using any backing materials.
