A102D焊条打底解决合金堆焊裂纹

TO OVERCOME HARDFACING CRACKS USING WITH A102D ELECTRODE BUTTERING

介绍了用A102D不锈钢焊条打底,D682焊条堆焊密炼机ZG310—570转子棱峰,解决了堆焊层裂纹问题。试验了堆焊层磨损减薄后对无隔离层和有隔离层硬度的影响。

Buttering with A102D stainless steel electrode on tch edges and comers of ZG310 - 570 rotor then hardfacing with D682 electrode there, the cracking problem is overcome. The effect with and without buttering layer on the hardness of worn off layer is tested.
