Fill in the blank: The quality factor for capacitive welding of pipes varies between 0.8 and 1.0, depending on _____, _____, and whether testing is done via sampling or 100% inspection. 1) All participants will receive a reward ； :):victory: 2) Please hide your replies; the method for doing this is: http://bbs.hcbbs.com/thread-492556-1-1.html. Do not edit the replies after posting them. 3) Answer: The level of radiographic inspection for single-sided welding and double-sided welding is specified in GB/T 20801-2006 \"Code for pressure pipelines – Industrial pipelines\", Guidelines, p. 32
Reply 1# security: All wrong. If you made a mistake, you’re dizzy
Full non-destructive testing, Partial non-destructive testing, Impossible to perform non-destructive testing, High difficulty; I’ll guess one

Reply 1# security: The quality coefficient Ej for weld joints should be determined based on the type of weld joint and the requirements for non-destructive testing of those welds, as well as the proportion of length to be inspected using non-destructive testing methods
Reply 1# security: no detection; sampling detection; 100% detection
Reply 1# security: I’m confused; I don’t understand. It could also be said to be based on the \"type of joint and the level of radiographic inspection\"”
100% testing, sampling testing, no testing
Reply to 1# security: Weld crack, is there a backing? Non-destructive testing
