摘要

The gas nozzle (2) for a welding torch (6) of laser-hybrid-welding head, comprises a sleeve shaped housing (35) with a discharge opening (25) for a welding wire, and a reception area for the reinforcement of the welding torch on an internal insert (28). A disk or plate shaped reception element (53) is arranged for contact tubes in the interior of the housing and electrically isolates the housing against to each other. The reception element for each contact tubes has a drill in which the contact tube is arranged. The gas nozzle (2) for a welding torch (6) of laser-hybrid-welding head, comprises a sleeve shaped housing (35) with a discharge opening (25) for a welding wire, and a reception area for the reinforcement of the welding torch on an internal insert (28). A disk or plate shaped reception element (53) is arranged for contact tubes in the interior of the housing and electrically isolates the housing against to each other. The reception element for each contact tubes has a drill in which the contact tube is arranged, and a connection unit, screw thread, elastic deformable break or plug element or locking device through which each contact tube is mounted in the housing. Both front side end areas of each contact tube protrude out from the reception element, which is formed through a break or plug connection device such as elastic support arm that encompasses each contact tubes. The housing has a positioning element such as recess or projection in the reception area for defined positioning at the internal insert. The housing has a fixing element for the production of gas tight connection between an internal surface of the housing and the internal insert of the welding torch.
