PROBLEM TO BE SOLVED: To expand usage of an after shielding tool and to improve its workability and reliability by providing a bend/deformation (flexibility) for the after shielding tool that is designed for gas shield (air insulation) of a weld zone in the welding of a titanium material or the like. SOLUTION: A trailer 2 of the tool is formed in a bisected cylindrical shape with an open bottom using a thin metallic material and made deformable. In the trailer 2, there is movably arranged an inert gas dispensing pipe which is formed in the cylindrical shape with the thin metallic material and made deformable. In addition, fibrous metal scrap 5 for diffusing the inert gas is arranged, and also a metallic net 4 is attached to the open bottom part of the trailer 2. COPYRIGHT: (C)2006,JPO&NCIPI |
