| Abstract: | It was explained how to choose the calibration standard, motor-driven rotating probe and inspection parameter for horizontal steam generator. The characters of the crack on the ligament, magnetism sign, denting sign and their complex signs were described, then the function of the magnetism saturation probe, sign classification, quality, orientation and quantitative analysis technique, and some technical problems which are needed to deal with in the future were introduced and summarized. |
