# §192.227. Qualification of welders and welding operators.

- (a) Except as provided in [paragraph (b)](#b) of this section, each welder or welding operator must be qualified in accordance with [section 6](/cfr/49/6.md), [section 12](/cfr/49/12.md), Appendix A or Appendix B of API Std 1104 (incorporated by reference, see [§ 192.7](/cfr/49/192.7.md)), or section IX of the ASME Boiler and Pressure Vessel Code (ASME BPVC) (incorporated by reference, see [§ 192.7](/cfr/49/192.7.md)). However, a welder or welding operator qualified under an earlier edition than the listed in [§ 192.7](/cfr/49/192.7.md) of this part may weld but may not requalify under that earlier edition.
- (b) A welder may qualify to perform welding on pipe to be operated at a pressure that produces a hoop stress of less than 20 percent of SMYS by performing an acceptable test weld, for the process to be used, under the test set forth in section I of Appendix C of this part. Each welder who is to make a welded service line connection to a main must first perform an acceptable test weld under section II of Appendix C of this part as a requirement of the qualifying test.
- (c) For steel transmission pipe installed after July 1, 2021, records demonstrating each individual welder qualification at the time of construction in accordance with this section must be retained for a minimum of 5 years following construction.
