Background
The fuel nozzle component consists of a thin-wall part head, a middle thin-wall part and a T-shaped tail end, and the fuel nozzle component is long in length, thin in wall thickness and large in number of formed single parts, so that the requirement on the length dimension of the fuel nozzle component is difficult to control in the argon arc welding process. Therefore, all the single parts are firstly subjected to positioning spot welding, and then argon arc welding is carried out on the welding positioning tool. Therefore, the fuel nozzle assembly argon arc welding positioning welding tool needs to be designed, the problem that after a single part is welded together through argon arc welding is solved, the size required by the design of an argon arc welding process can be guaranteed, the welding efficiency is improved, and the welding deformation caused by the welding stress of the part is controlled. The argon arc welding technology is a welding technology which utilizes argon gas to protect metal welding materials on the basis of the principle of common electric arc welding, melts the welding materials into liquid on a welded base material through high current to form a molten pool, so that the welded metal and the welding materials are metallurgically combined. The general fuel nozzle component is mainly made of high-temperature alloy and austenitic stainless steel, the argon arc welding performance is good, as the heat affected zone of the argon arc welding is large, large cold shrinkage stress exists after the argon arc welding, and the microstructure also has stress generated in the phase change process, and the stress can jointly act to enable parts to generate plastic deformation, so that the size and the precision required on the welding process are difficult to ensure, and the welding efficiency is reduced. The existing argon arc welding positioning tool cannot effectively limit the deformation of the argon arc welding positioning tool, so that the stability of the argon arc welding process is difficult to control, a large amount of manpower and material resources are wasted, and the difficulty of the welding process operation is improved. Therefore, the argon arc welding positioning welding tool for the fuel nozzle assembly is provided.
