    摘要: The present invention enables even a beginner to acquire the technique easily and perform suitable spot welding, and achieves improved workability, improved welding quality, improved productivity, and the like. The present invention includes a torch body 2 for passing a shielding gas, a tungsten electrode rod 5 inserted into the torch body 2 and connected to a cathode, a constricted nozzle 6 for supporting a distal end portion of the tungsten electrode rod 5 concentrically, defining a gas passage 6e between the tungsten electrode rod 5 and the constricted nozzle 6 for flowing a shielding gas G, and discharging the shielding gas G from the constricted nozzle 6 at a higher speed than the shielding gas G discharged from the distal end of the torch body 2, and a cylindrical electrode nozzle 7 having conductivity arranged concentrically with the tungsten electrode rod 5 on the outer circumference of the constricted nozzle 6, connected to the anode via a ground cable 18, and configured to have a tapered shape at a distal end portion, wherein the tapered distal end portion is located further outside than the distal end portion of the tungsten electrode rod 5, gas vent ports 7c and 7d of the shielding gas G are provided on the electrode nozzle 7.

    摘要: A build-up welding method is disclosed in which a welding torch is guided along a metallic workpiece and at least one melting wire serving as a build-up material is fed at an infeed speed into the arc between at least one non-melting electrode of the welding torch and the workpiece. In order to achieve a build-up welding method with higher build-up speeds in comparison to the prior art, it is proposed for the non-melting electrode positioned normal to the workpiece to be guided along the workpiece and for the fed wire to also be moved back and forth along its infeed direction.

    摘要: A welding torch includes a torch body and at least one device for feeding a consumable welding wire towards the tool center point that has an attachment device for attachment to the torch or an element connected thereto. A base support, which is connected to the attachment device, includes at least two deflection elements for guiding the wire towards the center point. The at least two deflection elements are arranged on the base support so that a first wire path length from the last deflection element located closest to the center point to the center point is shorter than a second wire path length between the last deflection element and a further deflection element as viewed counter to a main wire feed direction, and so that the arcuate wire has a greater segment height along the second path length than the segment height along the first path length.

    摘要: A TIG (Tungsten Inert Gas) welding torch (10) comprises a torch body (22), a collet (38a,b,c) for retaining a tungsten rod, and a back cap (42), in which the collet 838a,b,c) passes through an aperture in the torch body (22) from the front of the torch body (22) to the rear of the torch body (22), and is joined directly to the back cap (42) by a screw thread (40a,b,c), the collet (38a,b,c) being drawn backwards against a front section of the torch body (22), to close the collet (38a,b,c) and retain the tungsten rod when the screw thread (40a,b,c) is tightened.
