WELDER QUALIFICATION & WELDING PROCEDURE QUALIFICATION
MES provides laboratory testing for qualification of welders and weld procedures, as well as CWI weld inspection. We offer these services at an affordable rate with a rapid turnaround.
In today’s environment, there is an increasing emphasis placed on the need for weld quality and safety. Welder qualification to a specific code certifies that welders and welding operators have the ability to make sound welds. Organizations qualify welders or welding operators for each welding process used in production or construction welding. MES helps facilitate this process by providing the testing requirements for submitted weld coupons.
FULL SERVICE NDT & MECHANICAL TESTING
MES is a full-service weld procedure and welder qualification provider with complete in-house NDT and mechanical test resources to step you through the qualification process. Our staff includes Certified Weld Inspectors, ASNT Level II Inspectors, and materials engineers to help investigate weld defects. The MES weld testing lab offers rapid weld inspection services and a full-service machine shop to process weld coupons.
There are typically three steps involved in qualifying welders and welding procedure specifications. First, a weld procedure (WPS) must be developed which contains the minimum requirements specified in the welding code. Second, the user must qualify the WPS by submitting weld test coupons. Finally, each individual welder is qualified by creating weld coupons according to variables established in the WPS.
Without internally developed code requirements, many organizations use code established by the American Welding Society (AWS) typically dealing with structural codes for buildings and bridges and the American Society of Mechanical Engineers (ASME) for boiler and pressure vessel codes.
