THICK PLATE TORCH OF SUBMERGED ARC WELDING FOR EDGE PREPARATION

摘要

PURPOSE: An extreme thick plate torch is provided to weld a narrow gap with submerged arc while keeping the rectilinear degree of a wire, to remove welding trouble by regularly forming the right and the left slant angle of a tip with a position fixing bolt and to prevent an electric leakage by coating ceramic powder on a torch surface and drying the ceramic powder in a dry oven for a perfect insulation. CONSTITUTION: An extreme thick plate torch(6) welding with submerged arc, contains body portions consisting of a torch body(1) which keeps the rectilinear degree of the body portions and a weaving body which supports the horizontal slant of a torch tip(7) and converts a conductive nozzle feeding a wire(5); tip slant angle adjusting portions(2,8,9) which adjust the slant angle of the torch tip with force from the rotation of a rotating bar(9) after that a flexible supporter(2) supports the rotating bar and an adjusting nut(8) adjusts the rotating bar; electrode portions consisting of the conductive nozzle and the torch tip and transmitting power to the wire; and a welding flux feeding unit(4) produced in the shape of a welding flux injecting port(12). Herein, the torch body is made from stainless steel in 13mm of a thickness and the weaving body is made from chrome-copper alloy.
