Fourth, flaw detection steps and methods 1. Flaw detection steps (1) measuring the size of the ministries to observe the force of the site to determine the test location and testing methods. (2) cleaning magnetic particle testing sites, ultrasonic testing head placement site surface. (3) magnetic particle inspection. (4) magnetic detection flaw detection defects, the application of crack depth gauge to measure the depth of the crack. (5) make magnetic particle inspection record. (6) ultrasonic longitudinal wave detection. (7) Ultrasonic transverse wave testing. (8) make ultrasonic inspection record. (9) Write a comprehensive report on the non-disassembled flaw detection of the winch axle, see “Causal Analysis of Process Chart” for details.
