Abstract
PURPOSE: The external surface welder which can operate automatically, by installing the cutter for cutting the tack bead and the groove, just before the external surface welder, and by controlling the feed of the cutter and welder and the transportation from the internal surface welding to the cutting position, correspondingly to the advance of the steel pipe.
CONSTITUTION: At manufacturing the large diameter welded steel pipe according to the UO press system, the steel pipe is transported by the roller conveyer 55 after finishing the internal surface welding. The sensor 58 detects the tab plate 22 at the tip of the steel pipe 21, and stops the roller 55; and then, he marker 54 detects the position of the seam, and the turning roller 57 places the seam portion so as to face correctly upward. The pressure roller 28 and the milling head 34 are brought down, and the milling cutter 36 is rotated by the detecting head 39; hereby, the tack bead or the groove is cut of. The cut portion is cleaned by the cleaning brush 40, and then, the sensor 59 temporarily stops the brush 40. The second pipe is fed according to this preset. Next, the steel pipe is transported and is detected by he detecting head 47; after that, the submerged arc welding is carried out
