Abstract
The invention relates to the multiarc welding, in particular to four-arched welding, mainly of straight-seamed pipes of large diameter. A method of four-arched welding is disclosed. First, second and fourth arc on the motion of welding are powered by alternating currents with 120° phase shift relative to each other, and third arc - by direct current.
