Scope

This standard specifies the general method for detecting the fusion welds of bolt ball joint steel grid members and cone heads or sealing plates as well as steel pipe butt welds using single or double element oblique probe contact method ultrasonic flaw detection to determine the location, size and defect assessment of defects. Quality grading method. This standard is applicable to A-type pulse reflection manual ultrasonic flaw detection of ordinary carbon steel and low alloy steel rods and cone head or sealing plate welds and steel pipe butt welds with a base material thickness of 3.5mm-25mm and a pipe diameter of not less than 48mm. Quality classification of flaw detection results.
