结合国内外标准阐述了阀门密封面堆焊层厚度的确定原则 ,通过实验研究 ,得出了不同堆焊工艺方法产生不同稀释率的规律 ,从而合理确定堆焊层厚度。
According to the domestic and international standards, the principle of determining the thickness of the overlay layer on the valve sealing surface is expounded. The law of different dilution rates of different overlay welding methods is obtained through experimental research, so as to reasonably determine the overlay thickness.
