NCPWB Weld Bureau  Chapter 24

The National Certified Pipe Welding Bureau (NCPWB) is a subsidiary of the Mechanical Contractors Association of America (MCAA). NCPWB was established to keep contractors informed about welding/brazing technology, allow for the transfer of welder/brazer certifications, and to simplify the welding/brazing qualification practices.

As a contractor installing welded and brazed piping systems in accordance with ASME B31 Piping Codes, you are required to have welding and brazing procedure specifications and qualified welders and brazers as required by Section IX of the ASME Boiler and Pressure Vessel Code. Writing and qualifying welding and brazing procedures to meet Section IX requirements is complex and time consuming. You can save time by utilizing over 100 welding and brazing procedure specifications (WPSs and BPSs) that are qualified to ASME Section IX and are available for immediate use on piping without further qualifications. NCPWB works closely with the United Association (UA) in conducting welder qualification testing. This testing is done under a program that is accredited by the Hartford Steam Boiler Insurance and Inspection Agency and is in full compliance with ASME Section IX. Testing has been standardized and test information is stored in a national database, making it easy to find a welder locally. These welders are qualified to use the process and to weld on the materials that a contractor needs for a job. Welders can carry their certifications with them from one company to another and the company can rely on this seamless transition to save them time and money.

Membership in the NCPWB will entitle you to as many weld procedures and welder/brazer documents as you would like at absolutely no cost.
