Bob Rasooli explains how individuals with limited oil and gas industry experience can prepare themselves for any API 510, 570and 653 exams. If you are struggling with comprehending codes and standards in the above exams, the best solution is to start with API RP 577. The title of this API recommended practice is Welding Inspection and Metallurgy. However, the content is not limited to welding. It covers many aspects, introduces different material types, i.e., carbon steel, Austenitic stainless steel, nickel alloys, etc, and explains each material's properties. This RP also teaches you nondestructive examination, the conventional and advanced NDT, with straightforward, easy-to-understand language. So if you are troubled, start with API RP 577 and make a foundation for other codes and standards you must study. https://www.inspection-for-industry.c...
