  • Patent number: 9545683
    Abstract: A method and a welding device for performing a welding process on a workpiece by a welding torch, uses a melting welding wire, which is arranged on a wire coil and may be supplied to the welding torch via a hose package, wherein different welding wires and different welding parameters are used depending on the geometry of the workpiece. A welding wire formed by the different interconnected welding wires in lengths depending on the geometry of the workpiece is arranged on the wire coil, so the welding process may be performed without interruptions using the different welding wires and the different welding parameters by supplying to the welding torch the welding wire formed by the different interconnected welding wires from the wire coil.
    Type: Grant

  • Patent number: 8546727
    Abstract: The invention relates to a contact tube (29) for a welding torch (10), having a longitudinal axis (31) along which a through-opening (30) for guiding a welding wire (13) from an inlet region (37) to an outlet region (35) and from an outlet opening (39) towards a workpiece (16) is provided, wherein at least one slot (34) is provided in the outlet region (35) for making contact with the welding wire (13). A contact tube (29) with improved contacting of the welding wire (13) is obtained by providing at least one further slot (36) in the inlet region (37) of the contact tube (29), wherein the slot (36) in the inlet region (37) is arranged in line with the slot (34) in the outlet region (35), and a web (38), which serves as a pivot point, is formed between the slot (34) in the outlet region (35) and the at least one slot (36) in the inlet region (37).
