The state shown in FIGS. 1 to 5 is a weldable state, in which both electrode rollers 8 are strongly pressed against the flange 1a by the spring 19 of the urging means 9. When the drive motor 39 is operated from this state to rotate the electrode roller 8 in the direction of arrow A, this welding device moves forward. At the same time, welding transformer 2
1 to both electrode rollers 8 through the flexible conductor 23, and the flanges 1a are seam-welded by the heat generated by the contact resistance at that time.

Then, by seam welding, the painted steel plate 1
The paint is removed and the paint is baked onto the outer peripheral surface of the electrode roller 8, but the baked paint is scraped off by the cutting tool 31 which is pressed against the outer peripheral surface of the electrode roller 8 with appropriate pressure. Therefore, the surface of the portion of the electrode roller 8 that contacts the flange 1a is always exposed, and a predetermined amount of current can continue to flow between the two electrode rollers 8.
Even if it is a, it is possible to completely seam weld it from end to end.

Next, after welding flange 1a, the adjacent flange 1
When moving to step a, after the motor 39 has stopped, the urging force release lever 10 is rotated in the direction of arrow B (see FIG. 3). Then, the biasing force of the spring 19 is released,
Both arms 7 move away from each other, and electrode roller 8 also moves away from flange 1a. At this time,
Since the paint scraping device 11 also moves together with the arm 7, the relative relationship between the electrode roller 8 and the cutting tool 31 does not change, and there is no fear that the cutting edge of the cutting tool 31 will bite into the electrode roller 8.

Through the above operations, the welding device separated from the welded flange 1a is made to straddle the adjacent flange 1a,
When the biasing force release lever 10 is rotated in the direction opposite to the arrow B, the electrode rollers 8 again clamp the flange 1a, and seam welding becomes possible. At this time, when the welding device is moved backward for positioning, both electrode rollers 8 are rotated in the opposite direction of arrow A. However, since the tip surface of the cutting tool 31 is inclined 31a, the cutting edge of the cutting tool 31 is It will not be damaged by the electrode roller 8.
