    摘要： PURPOSE:To prevent automatically generation of thickness deviation in a weld bea in the TIG arc welding stage in which welding is executed while a welding torch is oscillated by controlling the vertical and lateral movement of the welding torch by the voltage from a welding voltage detector. CONSTITUTION:Base metals 1 having the groove formed into an inverted trapezoidal shape are welded by a filler wire 4 of an electrode 3 while the welding torch 2 is vertically and laterally moved according to the groove shape. The arc voltage during welding is detected by a detector 16 and the voltage is inputted to a control part 17 in order to execute constant arc length welding. The signal for the vertical axial position of the welding torch 2 detected by an encoder 14 is inputted thereto at the same instant. The control signal for the vertical axial movement of the torch 2 is fed to a motor 13 for a vertical axial slider 12 and the control signal for the lateral axial movement is fed to a motor 11 for a lateral axial slider 10 in the control part 17 to control adequately the vertical and lateral movements of the torch 2 in order to maintain the specified length of the arc between the wire 4 and the base metals 1, by which the weld bead having no thickness deviation is formed.

    摘要： PURPOSE: To subject the entire part of a square narrow groove continuously to gas shielded arc welding with good efficiency by disposing an auxiliary jig extending the groove to nozzle side with the narrow groove in-between on the nozzle insertion side of welding base metals.
    CONSTITUTION: In installing and welding a small diameter pipe 2 to a large diameter pipe 1 or the like, a groove forming auxiliary jig 23 is disposed on the nozzle insertion side of a square narrow groove 3 prior to starting of welding. This jig 23 is formed by using, for example, metallic plates, and disposing an outer ring 23a on the pipe 1 side and an inner ring 23b on the pipe 2 side wherein both rings 23a, 23b form bottom surfaces respectively conforming to the surfaces of the base metals and are disposed by tack welding or the like in such a way that a tentative auxiliary groove 24 is formed. Then, even if an insertion type shielding nozzle rises to near the top surface of the groove 2, it is located within the auxiliary groove 24 and therefore the shielding gas is effectively utilized and the need for such a step of exchanging the nozzle to a box type shielding nozzle is eliminated.

    摘要： PROBLEM TO BE SOLVED: To solve a problem that it is hard to secure a regular stable state of an arc due to existing of two different short-circuit periods: an extremely long short-circuit period in the case, when a predetermined time to distinguish a long-term short-circuit elapses from the time of generation of short-circuit, a welding current is decreased, the tip end of a wire is separated from a base material by retreating feed, and an arc is generated again; and a short short-circuit period in the ordinary case the time to distinguish the long-term short-circuit does not elapse.
    SOLUTION: During the short-circuit period from the time of generation of a short-circuit to the time of generation of an arc, a wire-feeding speed is decelerated to one lower than a base wire-feeding speed. An arc period from the time of generation of the arc to the time of next generation of short-circuit, the wire-feeding speed is accelerated back to the base wire-feeding speed. A predetermined peek current is output by a constant current control during the period from generation of an arc to a first predetermined time, a welding current is output by a constant voltage control during the period from generation of an arc to a second predetermined time, and then a predetermined base current is output by a constant current control.

    摘要： PROBLEM TO BE SOLVED: To provide a controlled short-circuit welding system capable of furnishing a welding wire over an extended time period and advancing and retreating the welding wire.
    SOLUTION: A reversible wire feeding motor displaces a wire to an arc or detaches the wire from the arc. A controller controls the reversible wire feeding motor so as to be reversed at least once every process cycle, and/or controls the power source so that the required average arc current can be supplied by the power source, and/or controls the reversible motor in response to short-circuit detection and short-circuit cancellation and/or controls reversal frequency in response to molten pool oscillation frequency. The controller includes an average arc current controlling module and/or a controlling module such as a short-circuit detection feedback circuit and the like. In another practical example, a reversible motor is a stepper motor which rotates increasingly at a series of steps having a prescribed angle. The controller includes a step size output power and the prescribed angle changes in response to the step size power output.
