Non-destructive testing issues for end caps
Thread Content
I would like to ask everyone: 100% flaw detection was performed on the head, and the inspection results were grade II, which is considered acceptable. Do we still need to do table exploration? Our on-site staff requests it to be done – where is the source? Thank you
Thank you all. I couldn’t find the correction sheet, so I never was able to locate its source; I learned from it.
It must be done; this is a requirement. Surface inspection and internal inspection do not interfere with each other. They do not affect each other.
Since surface cracks tend to form in such welds, and X-rays and ultrasound are prone to missing such cracks, surface inspection is required after welding.
