Scope: This document specifies the requirements for ultrasonic testing of austenitic stainless steel or nickel-based alloy weld overlay layers on the inner or outer surfaces of tubular components and valve bodies (hereinafter collectively referred to as components) in oil and gas wellhead equipment. This document applies to manual or automatic testing of weld overlay layers, fusion layers, and heat-affected zones with a diameter of more than 50 mm and a weld overlay layer thickness of 3 mm to 25 mm in components of oil and gas wellhead equipment during production, manufacturing, installation, and repair. The testing of weld overlay layers on other equipment components can be carried out by referring to this document.
