Abstract

PURPOSE:To obtain a good welding result without any suction of air from the nozzle screw part by moving the nozzle in the torch axial direction by turning a nozzle fitting metal and by fixing the nozzle with pressing it to a stepped part. CONSTITUTION:A nozzle fitting metal 8 is fitted not to be moved in the torch axial direction by stop rings 9, 10 on the outer periphery of a nozzle insulator 2. It is also fitted freely rotatably co-axially with the torch shaft core and the screw part for screwing in the nozzle 3 is provided on the inner diameter part. When the nozzle 3 is inserted into the nozzle fitting metal 8 is turned with holding the nozzle 3 in the prescribed direction, the nozzle 3 is moved upto the position where the end face of the nozzle 3 is pressed to the step part of the nozzle insulator 2. The nozzle 3 is thus fixed surely in an optional direction and the suction of the air from the nozzle screw part is eliminated.

The welding torch used for conventional gas-shielded arc welding is constructed as shown above. When the irregularly shaped nozzle is adjusted and fixed in any direction in the circumferential direction, the positional relationship between the nozzle tip and the tip tip changes. There were drawbacks such as the nozzle tip moving back and forth, and the end face of the nozzle not being in close contact with the stepped part of the nozzle insulator, which caused air to be sucked in from the nozzle thread, causing a shield failure.
