Dear Mr. Yuen:

This is in reply to your letter of May 17 1971, concerning qualification of welders who weld on pipe being operated at stress levels of less than 20% of SMYS.

We agree with your interpretations that a, welder who welds on pipe being operated At less than 20% of SMYS need only fulfill the requirements Of 49 CFR, Section 192.227(c). However, we cannot agree with the statement in the third paragraph of Mr. Anderson's letter where he states they “Consider the basic test to be all inclusive." Section 192.227(c) requires that welders who' make welded service line connections to mains qualify under Section II of Appendix C in addition to the basic test of Section I.

If we can be of further assistance, please let us know.

Joseph C. Caldwell

Office of Pipeline Safety
