<p>PROBLEM TO BE SOLVED: To provide a metallic pipe resistance-welding machine capable of simplifying the steps and improving the quality of a metallic pipe resistance-welding apparatus without depending on the level of skill of an operator.SOLUTION: A resistance-welding machine 300 or a resistance-welding device can perform a welding step work smoothly when the flange parts of cylindrical metal pipes are welded at a manufacturing process, because a clamp part 302 having the electrode A304 of the resistance-welding machine 300 is equipped with movable members 307 and 308 which are divided into a semicircular shape made turnable on a support shaft 306, and the welder electrode parts at the resistance-welding time can hold the cylindrical pipeline weld zone more reliably and stably.</p> |
