Weld Testing and Welder Certification Services

Weld Testing and welder certification verifies that specified welding procedures will create welds that are suitably strong and satisfy quality standards and/or code requirements. The purpose of qualification is to demonstrate and document that a joining method (or methods) can satisfy all of the design requirements of the finished product.

Welding qualification documents include:

  • Welding Procedure Specification (WPS) Summarizes all of the welding variables and materials used for many welds
  • Procedure Qualification Record (PQR) Documents the testing that was performed to qualify a particular procedure within the WPS
  • Welder Performance Record (WPR) Documents the results of and individual welder or operator to a WPS


IMR has AWS CWI's on staff at all of our US locations, as well as trained and knowledgeable experts at our labs in Asia.  Whether you need analysis on your raw materials such as solder wire, or a full weld qualification packages, we can get you the answers you need.
