摘要： PURPOSE: To reduce the cost in cleaning by providing a heating device to heat a seam part from the outer face of a pipe and by arranging a reflection body for heating the inner face of the pipe.
CONSTITUTION: A heating furnace 10 is installed on the center part of a sliding frame 2 to ascend and descend via a cylinder 3. A burner 13a together with a combustion chamber 13 is arranged on the upper end part of the furnace 10. An opening part 12 which is along the seam part is provided on the lower end part of the furnace 10 and also a reflection body 16 is suspended via a hanger 17. When a blank pipe is transferred, the burner 13a is ignited with detecting it by a proximity sensor and burnt. Consequently the seam part of the blank pipe 7 is heated by the radiated heat from the inside of the furnace through the opening part 12 and also heated by the reflected heat of the reflection body 16. With this method the seam part of the blank pipe 7 is effectively cleaned and the cleaning cost can be reduced.

摘要： PURPOSE:To improve the quality of weld joint and production efficiency by welding the coil tip groove formed by oxy-plasma arc cutting by tandem submerged arc welding method after welding it by large current MIG welding method. CONSTITUTION:In manufacturing spiral steel tubes continuously from relatively thick strip coils, the end of preceding coil and that of succeeding coil are cut by an oxy-plasma arc to form a welding groove. Then, the groove at the end of both coils is welded by large current MIG welding method. After solidification of the deposited metal, welding is made by tandem submerged arc welding method without melting the preceding deposited metal completely. By this method, generation of blowwholes in the deposited metal can be reduced and defective welding such as hot cracking, falling etc. can be eliminated to improve the quality of weld joint.

摘要： PURPOSE:To always execute stably an arc start by cutting and removing a spherical part of a welding wire tip which has been generated after welding has been ended, by a cutting machine which can move forward and backward. CONSTITUTION:When welding is ended, a cylinder 62 is operated by a control device, an arm 38 is turned counterclockwise, an air nipper 40 advances toward a torch 34, and the tip part (edge part) of the air nipper 40 reaches the lower part of the torch 34. A position of the nipper 40 is detected by a sensor 68, and controlled through the cylinder 62 by the control device. When the edge part of the nipper 40 reaches the lower part of the torch 34, high pressure air is supplied to the nipper 40, the part which has been projected from the torch 34 of a welding wire, namely, a spherical part is cut. The spherical part of the welding wire which has been cut drops as wire chip 56 into a wire chip receiving box 52. Thereafter, the nipper 40 is turned clockwise by the cylinder 62, withdrawn from the torch 34 and moved to a holding position, and also, the edge is opened, and the device is prepared for the next cutting.

摘要： PURPOSE:To perform edge bending of a steel plate accurately and efficiently by bending edges of the steel plate by roll forming and then correcting the irregular part in the longitudinal front and rear parts by press forming for edge bending work prior to the U working of UOE steel pipes. CONSTITUTION:Both edges of a steel pipe 1 are bent into a prescribed curvature by roll 2 and then the front and rear edges A and B formed irregularly are formed into the same shape as that of the intermediate part by a press prior to the U working. The steel plate 1 bent by the roll forming abuts on a stopper 11 of a press forming device on the pass line and is clamped through up movement of a lower clamp 9. The front and rear edges A and B are press formed into the prescribed shape by up-movement of a lower die 4. In this method, the edge bending of steel plates is performed accurately and efficiently.

摘要： PURPOSE:To improve the speed for the edge preparation and the pipe production efficiency, by forming a groove by plasma arc breaking and by connecting coils by submerged arc welding. CONSTITUTION:For the purpose of preventing waste of cathode (tungsten) 4 caused by the reverse current of plasma gas, argon gas Ar is flowed as protection gas around the cathode 4 slightly. This argon gas as protection gas is exhasuted from the part between the first tip and the second tip and is prevented from being brought into contact with steel plate 6 directly. Pure oxygen 0 as operating gas is jetted from nozzle 3 to generate plasma arc (f) between steel plate 6 as the anode and tungsten electrode 4 as the cathode by power source 5, thereby cutting off strip coil steel plate 6. After that, groove parts at both ends of coils are welded by the submerged arc welding method. Consequently, the breaking processing time is shortened, and the connection time is shortened corresponding to the shortaned portions of the cutting time.
