Methods of liquid penetrant testing and classification of indication for steel castings Dye penetrant examination of the completed weld. GB/T9443-1988铸钢件渗透探伤及缺陷显示迹痕的评级方法对已完成的焊缝进行着色渗透检测。
Liquid penetrant testing is widely used in weld examination and pressure equipment inspection, but its performance in low temperature is poor. 渗透检测广泛运用于焊缝和锅炉压力容器检验中,但低温环境适用性差。
