This standard specifies the metal magnetic memory detection method for welded joints of pressure equipment and the principles for processing the detection results. This standard is applicable to metal magnetic memory detection on the welding streets of pressure-bearing equipment such as power station boilers, pressure vessels, and pressure pipelines in service. The detection of other electrical equipment can be carried out by reference.
