耳环是航空发动机焊接组合件稳定器上的一个承力元件,原由精密铸造而成。铸件要经过多道机械加工工序,工艺复杂,并且铸件较厚,零件单台重量也较重。为了适应新型发动机提高推力、减轻重量的要求,零件由铸造结构改为板材焊接结构,由左右两个耳片组成(图1)。A段为电阻焊,B、C、D处为氩弧焊;材料为GH3128,厚度为2毫 Earrings are a load-bearing element on the stabilizer of aeroengine welding assembly, originally made by precision casting. Castings to go through multiple machining processes, process complexity, and thick castings, parts, single weight is also heavier. In order to adapt to the new engine to improve the thrust, reduce the weight requirements, parts from casting structure to plate welding structure, by the left and right two ears (Figure 1). A section of the resistance welding, B, C, D Department of argon arc welding; material GH3128, a thickness of 2 milliamperes
