溶接装置。 A seam welding device that performs seam welding by rotating each of the electrode rollers while sandwiching and pressurizing a band-shaped welded part where two sides of a metal plate overlap with each other with a pair of electrode rollers, and supplying welding current between each of the electrode rollers. , a welding current supply means for supplying a welding current between the pair of electrode rollers, a detection means for detecting a relative position of the welded part with respect to the pair of electrode rollers, and a steady state other than both ends of the welded part. a first setting means for setting a welding current necessary when welding the parts, a second setting means for setting a welding current necessary when welding both ends of the welded part, and a detection means. control means for instructing the welding current supply means to output the welding current set by the first setting means or the second setting means, based on the detection result; The first setting means outputs a first setting voltage based on a constant voltage, and the second setting means outputs a second setting voltage based on the first setting voltage output from the first setting means. A seam welding device that outputs voltage.
