Abstract
PURPOSE: To accurately and effectively carry out the tack welding, by rotating expanding and squeezing apparatus correcting the dislocation of groove line at the inside of pipe and providing the dislocation detector just before the tack weld zone.
CONSTITUTION: The pipe 1, 2 are placed on the turning roller 6 and the expanding and squeezing apparatus 10 is inserted in the groove line in the pipe. The squeezing rod 12 is projected by inducing oil pressure and next, the squeezing rod 11 is projected and is energized. Tack welding is carried out by the welding machine 20 stopping the induction of oil pressure, when the permissible limit of dislocation is dectected by the dislocation detector 50. The tack welding of the pipe is carried out rotating by the roller 6 and the apparatus 10 is rorated continuing stretching by the order of the detector. Welding is interrupted when the dislocation is detected by the detector 50 and energizing of the apparatus 10 is removed stopping the rotation of the pipe and the welding is continued stretching again unitil disloction is not detected
