摘要： An automatic welding apparatus for non-consumable-electrode-type arc welding comprises a mechanism which is adapted to feed a second wire in the molten pool and to oscillate this second wire in synchronism with the oscillation of the welding torch and the conventional wire and at a position where both wires are opposed to each other in an axis perpendicular to weld line.An automatic welding apparatus for consumable-electrode-type arc welding comprises a mechanism which is adapted to feed a second wire in the molten pool and to oscillate this second wire in synchronism with the oscillation of the welding torch and at a position where both wires are opposed to each other in an axis perpendicular to weld line.

摘要： A semi-automatic TIG welding apparatus including a torch handle, a wire-feeding curved nozzle which is disposed within the torch handle and is curved at a point slightly extended from the torch handle, and a TIG torch supporting arm which is fixed to a TIG torch having a shielding gas hose and center gas hose. An inside portion of the TIG torch supporting arm is formed of an electroconductive material. The apparatus further includes water-cooling welding cable hoses which are attached to a water tank, extend through the inner side of the torch handle, and are attached to the TIG torch. The water-cooling welding cable hoses being formed with electroconductive cables provided therein. The apparatus may additionally include a TIG torch rotation block which is rotatably mounted to the wire-feeding curved nozzle and fixed to the TIG torch supporting arm. Thus, a semi-automatic TIG welding apparatus is provided wherein a TIG welder can freely adjust the position of the welding wire, and wherein the welding wire can be inserted to an ideal position, and also wherein the wire-feeding curved nozzle and thus the wire do not fluctuate in position, resulting in great savings in the expense and time related to TIG welding, and also in the amount of labor on the part of the welder.

摘要： A method of welding metal products, at least one of which is made of nickel or a nickel alloy, comprises the steps of generating an arc between the products to be welded, serving as a positive pole, and a tungsten electrode held by a welding torch, serving as a negative pole. A shielding gas is emitted, consisting of an argon-based mixed gas containing one or both of hydrogen and helium, from a confining gas nozzle concentric with the tungsten electrode, thus confining the apparent flaring angle of the arc within 80 degrees. The welding torch is moved along the weld line while feeding the tip of a filler wire to a part of the molten pool directly below the arc. This method is applicable to the welding of metal products, at least one of which is made of nickel or a nickel alloy.
