Most manufacturing enterprises mainly produce the welding structures of various parts according to abundant experiences and various test data when designing and producing the welding structures of various parts, and a large amount of time can be wasted by adopting the mode. In daily life, the welding method of the pipe fitting and the flange is mainly that the flange and the pipe fitting are riveted and then are subjected to single welding, and the welding deformation is large under the condition that no welding tool or optimized welding process exists. The welding tool has the structural characteristics that the welding tool comprises a clamping mode of the tool, the welding precision of the pipe fitting and the flange is greatly influenced, and the pipe fitting and the flange are easy to deform during welding. Through the prediction and control of the welding deformation of the reinforced pipe fitting and the flange, the welding quality can be improved, and a large amount of welding time is saved. Because the requirement on the precision of a welding structure is higher, an operator needs to increase the welding deformation control force, if the welding link deforms in a large area, the manufacturing period of the parts is prolonged, the production efficiency of the parts is reduced, and the economic benefit of an enterprise is greatly influenced. Through being used for flange welding deformation to the pipe fitting and carrying out accurate prediction to formulate the better control measure of feasibility, can guarantee that barrel flange welding quality obtains better promotion, and then improve the economic development level of enterprise.

The reason for tracing the welding deformation is mainly that the welding is carried out after the flange sheet is welded after being measured and aligned for many times by a square ruler, and the deformation is generated due to the influence of an uneven temperature field generated in the welding process of a weldment, so that the angle between a pipe fitting and the flange is changed and deviates from the angle requirement of a normal right angle by 90 degrees, and the welding deformation is related to factors such as the shape and the size of the weldment, the physical properties of materials, the welding method and the like. Under the condition that the structural design of the flange and the pipe fitting cannot be changed, the optimal method is to optimize the welding process and manufacture the welding auxiliary tool.
