Abstract

PURPOSE: To realize faultless TIG welding even in a narrow groove by completely shielding the atmosphere, by providing side shield nozzles having gas injection holes opened in three directions in the torch main body, and fitting a slidable ring gas tube with skirt externally thereto.
CONSTITUTION: A torch main body 1 and side shield nozzles 4, 4 are positioned in the narrow groove of the work, and a welding machine is so set that the inner face of a skirt 14 in the lower part of ring gas tube 11 may abut against the upper face of the work, and is moved along the groove. In this case, the inert gas flow from a ring gas passage 3 is injected so as to envelope the welding position and the surrounding thereof. Further, an inert gas curtain is formed on the outer circumference side of the torch main body by the gas flows from gas injection holes 8W10 in the nozzle opened in the directions of the main body, both sides, and downwards of the torch main body. Besides, since the skirt 14 covers the outer circumference side of the nozzle, the atmosphere may be discharged and cut off completely.
