AVC TIG Orbital TIG welding apparatus with two torches including a separated AVC axis

摘要

The present invention provides an orbital welding apparatus for welding while traveling on a rail (10): a main body (20) having a leading torch (21) and a trailing torch (22); A wire feeding part 30 feeding each wire to the preceding torch 21 and the trailing torch 22; And a controller 40 that adjusts the arc length of the preceding torch 21 and the trailing torch 22 to a predetermined pattern. Accordingly, by mounting two torch which can adjust the arc length by independent height control, there is an effect that can improve productivity during welding of pipes.
