Abstract

PURPOSE:To provide a titled device which permits easy and stable welding and straightening without changing the preparatory plan for the operation by providing a mechanism which holds freely rotatably a main pipe or the like from both ends and drives rotationally said pipe and a mechanism for pressing the pipe. CONSTITUTION:A pin 22 or 23 fitting to the flange 2 of a main pipe 1 is usably prepared and the pipe 1 is hoisted with a crane to insert one end thereof onto the stepped shaft part 21 of a driving shaft 10. The pin is inserted into the hole of the flange 2. A mechanism 17 for supporting a driven shaft provided in the rear end position is then moved to insert the stepped shaft part 36 thereof to the other end of the pipe 1 and the mechanism 17 is fixed to a rail 16. A motor 27 is thereafter started to rotate a branch pipe 3 attached to the pipe 1 to the angle at which welding in a flat position is accomplished and a pressing mechanism 18 is moved to an adequate position. A pressing clamper 41 is lifted in this stage to press the pipe 1 and welding is performed in the state of applying reverse strain thereto. The pipe 1 is again rotated to an adequate angle after the welding a semicircle of the branch 3 and welding is performed in the state of applying the reverse strain to the pipe by the clamper 41 in the same way as before.
