<p>A copying welder, comprising a carriage allowed to self-travel forward and backward, a welding torch mounted on the carriage, a weaving drive part weaving the welding torch, a copying mechanism running the carriage along a specified running route, a welding torch holding part for holding the welding torch through the weaving drive part and holding the weaving drive part so that the position thereof can be adjusted in order to rotate a weaving route about a weaving center, whereby, even when not only welding is performed on a generally horizontal carriage running surface and a generally vertical carriage running surface but also performed on an inclined carriage running surface, a multi-layer buildup welding can be performed without causing an unbalance of buildup amount between a buildup part on an inclined carriage running surface side and a buildup part on a copying surface side.</p> |
