Certified Welding — ASME IX and CWB: What It Changes
August 10, 2025 5 min read
ASME IX and CWB 47.1/47.2 are not labels — they govern WPS, welder qualification and traceability. Here is what that changes for your projects.
A WPS for every situation
A welding procedure specification (WPS) sets the process, the parameters, the filler metal and the position. It is qualified for a given material, thickness and diameter. No suitable WPS, no certified weld.
ASME IX covers welder and procedure qualifications; CWB 47.1 applies to steel and CWB 47.2 to aluminum.
Traceability for audits
Every weld is identified and tied to a welder and a WPS. Parameter records and joint identification let inspectors validate compliance and make audits straightforward.
Qualifications kept current
A qualification is not a one-time achievement. It is renewed and maintained, especially for specialty alloys like duplex, copper-nickel, titanium, Monel and Inconel.
