Welding Services, Program Development & Qualification

Weld qualification, certification testing, and program development with expert consultation

Welding programs often fail not because the welding is wrong, but because the qualification process is poorly planned. Procedures that do not anticipate future production variables require requalification. Welder tests performed against the wrong parameters have to be repeated. When code requirements are not fully understood at the outset, gaps emerge during audits or project submittals, often at a critical time. 

MISTRAS provides weld procedure qualification testing, welder and welder operator qualification, and welding program development services that address these problems before they occur. Our certified welding inspectors take the time to understand what each client is building, what codes govern their work, and how to design a qualification program that will serve their current project and their future production needs.

With in-house welding booths and a full mechanical and metallurgical testing laboratory, MISTRAS delivers comprehensive testing capabilities supported by deep technical expertise and practical field experience. This enables an average turnaround time of four to seven days, compared to the industry standard of two to three weeks. The result is a combination of technical depth and responsiveness that fabricators and manufacturers depend on. 

MISTRAS welding program services

Building or maintaining a welding program requires more than knowing what tests to run.It requires an understanding of how today's qualification decisions affect future production flexibility. MISTRAS works with clients to establish, update, and expand certified welding programs, providing expert guidance on code requirements and supporting the design qualification programs that meet both current project needs and long-term production goals. Where existing programs are outdated or incomplete, we help identify gaps and close them efficiently.
