Abstract

PURPOSE: To prevent a short circuit of both welding end parts due to scale, etc., and to execute electro-unite welding completely, by placing a specific induction coil for stopping a short-circuit current when the welding end parts in the upper part of the welding part, in a high frequency electro-unite welding method.
CONSTITUTION: When a long steel pipe is manufactured by moving band steel 10 in the lengthwise direction, forming a roll, butting its both side end parts 10a, and performing the resistance welding by a high frequency current, an induction coil 18 connected in series to a welding load against a welding electric power source is provided on the upper adjacent part of a butt welding part 10b. In this case, the direction of a current iϕ flowing into the coil 18 is set so as to be opposite to a welding current (i). When performing a welding work, even if scale 16 scatters and short-circuits the both side end parts 10a, the short-circuit current is offset by voltage of the opposite direction, which has been induced by the induction coil 18, a welding current supplied to the welding part 10b is bypassed, is not reduced, and an excellent welding finished part 10d is formed.
