A WPQ is a welder test certificate that shows your welders are qualified for the job at hand.
This includes welding to the specifications of a particular standard and showing they are able to use the correct welding materials, processes and recommended procedures. Once your welders have completed the test weld we use destructive weld test to determine that the welds meet the specified standard and quality. Once the welder has achieved an acceptable result they will receive a welder test certificate, the WPQ.
A welding procedure qualification is necessary to ensure the quality and longevity of your welds. Each standard has their own minute details that require guidance from experienced professionals and Certified Welding Inspectors, like those at Akron Testing Laboratory and Welding School, Ltd.
