Abstract

PURPOSE: A torch structure which is capable of applying high-current MIG welding and also of preventing failure of fusion, having a mechnism in which the first and second shield boxes are mounted on periphery of nozzle portion the tip of which has feed tip.
CONSTITUTION: The periphery of the nozzle portion 1 is wholly mounted with the slender shield box 5 which is in turn inserted into the direction of thicker plate in beveling portion. The periphery of the first shield box 5 is provided with the second shield box 6 to which a torch supporter is fixed upward. In welding of narrow beveling portion, the welding of the first layer is made by lowering the first shield box 5 with the nozzle portion 1 while jetting a shield gas from the second shield box 6. Then, the welding is abvanced while rising welding point gradually toward the surface of plate. In this, the first shield box 5 and the nozzle portion 1 are jointly moved to make the seal between the air and welding point complete, thus ensuring the exact welding of narrow beveling portion of thick steel plates
