WRC - The Welding Research Council brings together science and engineering specialists in

developing the solutions to problems in welding and pressure vessel technology. They exchange

knowledge, share perspectives, and execute R and D activities. As needed, the Council organizes

and manages cooperative programs.

MPC – A Council of the WRC, the Materials Properties Council is dedicated to providing

industry with the best technology and the best data that can be obtained on the properties of

materials to help meet today’s most advanced concepts in design and service, life assessment,

fitness-for-service, and reliability and safety.

PVRC – A Council of the WRC, the goal of the Pressure Vessel Research Council is to

encourage, promote and conduct research in the field of pressure vessels and related pressure

equipment technologies, including evaluation of materials, design, fabrication, inspection and

testing.
