API 577

Welding Inspection and Metallurgy

API RP 577, Welding Processes, Inspection, and Metallurgy, is a recommended practice developed and published by the American Petroleum Institute (API) that provides guidance to the API authorized inspector on welding inspection as encountered with fabrication and repair of refinery and chemical plant equipment and piping. Common welding processes, welding procedures, welder qualifications, metallurgical effects from welding, and inspection techniques are described to aid the inspector in fulfilling their role implementing API 510, API 570, API Std 653 and API RP 582.

The American Petroleum Institute offers API RP 577 certification training and exams for inspectors and Welding Engineers. Certification under API RP 577 is valid for a three year term. While it was once mandatory for applicants to have prior certification for API 510, 570, or 653 before one could be certified for API RP 571, 577 or 580; as of 2013 this is no longer the case, and this standard is now completely individual and stand-alone.
