There are several ISO standards for welding inspection but none for qualification and certification of Welding Inspection Personnel. AWS (American Welding Society) offers CWI (Certified Welding Inspector) and together with the British CSWIP (Certification Scheme for Welding and Inspection Personnel) are the two most prominent and widely recognized certifications in the world.ĪPI offers a similar qualification under API 577 (Welding Inspection and Metallurgy) that is covered under our API preparatory courses.
