To suppress leakage from a mold of molten metal, in a welding device capable of padding on an inner peripheral surface of tubing.SOLUTION: A welding device has two molds each provided with a contact surface to be brought into contact with an inner peripheral surface of tubing upon welding, and arranged mutually separately, a welding torch for padding on the interval between the two molds, and a support member for supporting the two molds and the welding device, in which the two molds are relatively movable to the support member, and further has an energization means for energizing the two molds toward the inner peripheral surface of the tubing.SELECTED DRAWING: Figure 3 【課題】管材の内周面に肉盛溶接できる溶接装置において、溶融金属の金型からの漏れを抑制する。【解決手段】溶接装置は、溶接時において管材の内周面に接触させる接触面が設けられており互いに離れて配置されている２つの金型と、２つの金型どうしの間に肉盛溶接をする溶接トーチと、２つの金型および溶接装置を支持する支持部材とを有し、２つの金型は支持部材に対して相対的に移動可能であり、２つの金型を管材の内周面に向けて付勢する付勢手段をさらに有する。【選択図】図３
