摘要： PROBLEM TO BE SOLVED: To provide a method and a device for back bead welding, by which protruding back beads can be formed on a back face of a welding surface when the back bead welding is performed in upward posture. SOLUTION: End parts of pipes 10c, 10d are abutted at each other and circumferential welding is performed along the welding line formed between the pipes 10c and 10d. Arc is radiated from a welding torch 21 having a non-consumable electrode 22 at a welding wire 31 having a welding piece 32 at the tip end to form a molten pond and DC current I is made to flow in the direction along the welding line. Simultaneously when the current I flows, it is supplied to a coil 51 set along the circumferential direction of the pipes 10d, 10d to impart an electric magnetic field B in the direction orthogonal to the welding line. Thus, Lorentz force F is generated by the current I and the magnetic field B and protruding back beads are formed by making the Lorentz force F act on the molten pond. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To prevent the occurence of a welding defect by covering a torch tip part with an outer cylinder, which is bisected in the axial direction and connected through an expandable member, and making an outer cylinder tip open/close through oscillation around an axis orthogonal to a torch axis so as to suppress the entrapment of outside air to a groove. SOLUTION: An outer cylinder is such that bisected nozzle outer cylinders 5a, 5b are connected through a bellows 7 having an upper part of narrow width and a lower part of wide width. The nozzle outer cylinders 5a, 5b, while overlapping part of its upper end part, are mounted on an auxiliary nozzle mounting ring 4 of a torch main body 1 and made oscillatable around an axis orthogonal to a torch 1 center axis. Further, the nozzle outer cylinders 5a, 5b are energized to be in an open state on a normal condition. By this method, during welding, lower ends of the nozzle outer cylinders 5a, 5b and both side walls of a wide width groove are kept in a contact state with each other, outside air entrapment in the groove is suppressed. Further, the shielding effect in using a shield gas 8 from a shield gas pipe 9 is improved.

摘要： PURPOSE:To obtain the device, in which deformation of wrinkle in bending part and flattening, etc., developed at the time of bending with high frequency heating can be prevented. CONSTITUTION:One end of the metal tube 6 to execute bending is fixed to an arm 3 rotatable around a rotary shaft 7 and the other end thereof is clamped with a pressing device, and further, this tube is guided with a supporting roll 4. Then, the metal tube 6 is inserted into an annular high frequency heating coil 1 connected with a high frequency power source without any contacting. On outer periphery of the annular heating coil 1, an auxiliary coil 2 is arranged together with the coil 1 only to back side of bending in the tube 6 to be worked. Under this condition, at the time of supplying the constant current from the high frequency power source 5, as the current density conducting the coil 1 and the auxiliary coil 2 is lower than the current density conducting only the coil 1, temp. difference between the back side and the front side in the bending, becomes at about 300 deg.C. In this result, by difference of deforming resistance due to temp. difference in deforming part, neutral axis of the bending is shifted to the back side and thin ned thickness ratio at the back side is restrained, and deformation of the bending part accompanied with the work is prevented.

摘要： PURPOSE:To extend the service life of a welding wire electrification part and to stabilize welding by providing plural rollers to the electrification part and pressing a wire and supplying a heating current to the wire. CONSTITUTION:In nonconsumable electrode welding, the roller type electrification part 9 is arranged to the root of a guide chip 1 and connected to a wire heating power source 8. A nonconsumable electrode 5 is arranged to base metal 6 to be welded and the wire 2 is supplied to the guide chip 1 from a wire reel 3 via the electrification part 9 to perform nonconsumable electrode welding. At this time, fixed rollers 11 and a movable roller 13 are arranged respectively to the electrification part 9 and the pressing force of the wire 2 is adjusted by a pressing force adjustment bolt 15. Since the electrification is executed while pressing the wire 2 via the rollers 11 and 13, wear of the electrification part 9 is reduced. Further, since deformation of the electrification part 9 is prevented, the service life of the electrification part is extended and welding is stabilized.

摘要： PURPOSE:To improve the welding workability by fixing a groove cross section between the branch pipe groove face and the base pipe surface extending over a full circle of a joint to perform the welding. CONSTITUTION:A bevel angle phi of a branch pipe 2 is expressed with a formula I as a function of its coordinate angle theta and a welding robot 8, a microcomputer 9, etc., are arranged in combination. The lower edge of the branch pipe 2 is formed to a shape having the level angle phi based on the formula I via an NC gas cutting machine, etc., and then, the edge penetration along the base pipe outside diameter is carried out. The groove shape dimensions such as a groove width, a groove angle, etc., in case the branch pipe 2 is fitted to the base pipe 1 and the tack welding is performed are calculated. Next, the object position of the welding at the time of the automatic welding via a robot 8 and a computer 9 is calculated to perform the welding. By this method, since the welding with the fixed groove cross section is performed, the full-circled welding can be performed with the same number of beads. Accordingly, the welding workability is improved.
