    摘要: Disclosed is a tip separation apparatus of a welding gun, which mechanically separates consumable tips installed at the end of the welding gun in a robot welding machine. The tip separation apparatus includes tip seating stands coupled to a main plate configured to maintain level, and configured such that each of the tip seating stands has a first insertion hole, into which a corresponding one of tips coupled to fingers of the welding gun is inserted, tip separation units rotatably disposed on bottom surfaces of the tip seating stands and configured to press outer circumferential surfaces of the tips inserted into the first insertion holes of the tip seating stands so as to clamp the tips and to rotate the clamped tips so as to separate the tips from the welding gun, and a housing configured to rotatably receive the tip separation units in a state of being elastically supported.

    摘要: Insulated electrode fixture has an electrically conductive body with a receiving channel configured to receive a workpiece and an insert that is electrically isolated from the electrically conductive body is located on the first side and circumferential to the receiving channel. During welding processes, portions of the surface of the electrode fixture are electrically insulated from contact by a weld upset by the electrically isolated insert. Variations include an electrically isolated insert located on or inset into the surface of the electrode fixture, an insert of a non-conductive material located on or inset into the surface of the electrode fixture, an insert with a coating of a non-conductive material located on or inset into the surface of the electrode fixture, a non-conductive coating on the electrode fixture (except for in areas designated for conducting the weld current during resistance welding), or combinations thereof.

    摘要: A method for electric welding a workpiece arrangement having at least one workpiece with the aid of a robot arrangement including at least one robot. A rotational movement is carried out between the workpiece arrangement to be welded and at least one welding electrode which contacts the workpiece arrangement. The rotational movement is started as a function of a commanded and/or detected welding start and/or ended as a function of a commanded and/or detected welding end. The direction of rotation of the movement may be changed as a function of a predefined parameter during contact between the welding electrode and the workpiece arrangement.

    摘要: An opposing electrode determination method includes a step of inserting a pair of opposing electrodes into corresponding receiving portions, respectively, by holding, between the pair of opposing electrodes, a held member formed with the receiving portions on both sides; a step of measuring the inter-electrode distance between the pair of opposing electrodes; and a step of determining, based on the inter-electrode distance, whether a combination of the pair of opposing electrodes is correct or incorrect. The receiving portions are configured to have different insertion allowances for the opposing electrodes, respectively, according to the tip shape of each of the pair of opposing electrodes.
