API RP 577 - Welding Processes, Inspection, and Metallurgy

Explore this topic

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 inspectors on welding inspection as encountered with fabrication and repair of refinery and chemical plant equipment and piping. API RP 577 was originally published in 2004, and the most recent 3rd Edition was released in October of 2020.

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.
