Beschreibung
Zusammenfassung:	The invention discloses a method for reducing the welding deformation of heterogeneous materials, and the heterogeneous materials are two materials with different thermal expansion coefficients. The method comprises the following steps: obtaining the physical performances of the heterogeneous materials, carrying out the welding simulation of the heterogeneous materials through finite element analysis, and determining the maximum deformation caused by the welding stress of the heterogeneous materials; selecting a balancing material, marking the thermal expansion coefficient of the first material as X ppm/DEG C, and the thermal expansion coefficient of the balancing material as X +/-5 ppm/DEG C; carrying out welding simulation on the heterogeneous materials and the balance material through finite element analysis, and determining the thickness of the balance material; and welding the balance material and the second material to form a welding structure of the first material, the second material and the balance m
