Abstract

PURPOSE: To efficiently manufacture the product joined by weld zones of uniform quality, by first tack welding the front side before full welding the backside, and then, by cutting the tack welded zone for preparation of the groove shape on purpose to apply the full welding to the front side.
CONSTITUTION: The pipe 1 is prepared by, for instance, the shaping method for the UOE steel pipe, that is, the outer surface is first tack welded and then the inner surface is fully welded; this pipe 1 is transported in the arrowed direction by the roller conveyor 15a. When the detector 22 detects the leading tab plate 9a, the conveyor 15a is stopped. The cylinder 14b lifts the turning roller 14a which rotates the pipe 1 so as to located the tack seam A just above. The press roll 16 pushes the pipe 1, and at the same time, the cutter 18b starts the removing work for the tack seam and the groove preparation. The conveyor 15b transports the pipe 1 at a specified speed into the arrowed direction; when the detector 23 detectors the leading tab plate 9a, the outersurface-welder 12 starts the welding work. When the rear tab plate 9b passes over the detector 22, the cutting work is stopped; and when the tab plate 9b passes over the detector 23, the welder 12 is also stopped.
