The American Welding Society (AWS) provides a programme for welder qualification and the AWS National Registry of Certified Welders. Welding certification is proof that a welder has passed basic welding qualifications required to perform welds commercially. The Certified Welder (CW) programme tests welders on procedures used in the structural steel, petroleum pipeline, sheet metal and chemical refinery welding industries.There is a provision to test to a company-supplied or non-code welding specification. Certified Welder (CW) tests are performed at AWS Accredited Testing Facilities located across the world.
