CRI CRI Acceptance Criteria & Discontinuity Evaluation 2

Question 1

Which ASME acceptance standard applies to radiographic examination of pressure vessel welds fabricated under Section VIII Division 1?

Accepted Answer

UW-51 and UW-52

Answer

ASME Section VIII Division 1 paragraphs UW-51 (spot RT) and UW-52 (full RT) govern acceptance criteria for pressure vessel weld radiographs.

Question 2

An elongated indication whose length is greater than three times its width is classified as which type?

Accepted Answer

Linear

Answer

Any indication with a length-to-width ratio exceeding 3:1 is classified as linear under standard radiographic acceptance criteria.

Question 3

Under ASME B31.3 normal fluid service, what is the maximum acceptable rounded indication score for a full radiograph of a weld in material 3/4 inch thick?

Accepted Answer

10

Answer

ASME B31.3 Table 341.3.2 sets the maximum rounded indication score at 10 for normal fluid service welds up to 3/4 inch thickness.

Question 4

Cold lap (overlap) in a weld radiograph appears as which characteristic image feature?

Accepted Answer

A dark, irregular line along the weld toe with smooth edges

Answer

Cold lap appears as a dark irregular line at the weld toe representing unfused metal that has rolled over without bonding.

Question 5

When a radiographic indication is found to be JUST at the acceptance limit, what is the correct CRI action?

Accepted Answer

Accept the indication if it exactly meets but does not exceed the limit

Answer

Standard radiographic acceptance criteria are inclusive—an indication that exactly meets the limit (does not exceed it) is acceptable per the governing code.
