Abstract
PURPOSE:To complete back shielding by following the weld line of a curved face by refractably linking the shielding box body divided into the front and back, fitting it liftably to the upper part of a welding torch and providing a shielding gas pipe at the inner part of the shielding box body and a roller at the lower part. CONSTITUTION:A shielding gas is fed to a torch as well as an electric power is fed to a tungsten electrode 18 and when a shielding box 20 is moved along the weld line inside a curved face with feeding a shielding gas to shielding gas pipes 10, 11, the respective shielding box front and back parts 6, 7 execute a refraction motion centering around a pin 9 with the respective roller 16, 17 of each shielding boxes 6, 7 coming into contact with the base metal surface and are deformed by following the curved face. Therefore even in case of a tungsten electrode 18 being welded by repeating the vertical movement inside a groove shielding boxes 12, 13 keep a fixed gap at all times with the base metal, a shielding effect is obtd. and stabilized arc welding can be executed.
