TORCH FOR POWDER PLASMA BUILDUP WELDING |
摘要 |
A torch for powder plasma buildup welding capable of readily attaining welding in conformity to any size of a pipe material to be subjected to welding, any configuration thereof and the like. A torch head is replaceably connected to a torch body. The torch body is provided with a gap formation spacer member which is abutted against an inner peripheral surface of the pipe material to keep a distance between an opening of a convergent nozzle of the torch head and the inner peripheral surface of the pipe material substantially constant during buildup welding. Also, the torch body is provided with a deflection restraint spacer member which is abutted against the inner peripheral surface of the pipe material to prevent deflection of the torch body in the pipe material during buildup welding.
