MANUAL GAS TUNGSTEN ARC WELDING TORCH STRUCTURE FOR NARROW GAP JOINT

摘要

PURPOSE: A manual gas tungsten arc welding torch structure for a narrow gap joint is provided to reduce a welding area and a welding time and to reduce the deformation of a base material due to a welding process. CONSTITUTION: A manual gas tungsten arc welding torch structure for a narrow gap joint comprises a body(1), an electrode rod(4) and a gas nozzle cap(3). The protective gas flows in the body. The electrode rod is projected on the center of inside of the body in a vertical direction. The electrode rod is made of copper. An inclined hole(411) is punched on the end part of the electrode rod.
