The safety and cost-effectiveness of welding is critically dependent on the skill of individual welders. Welders seeking to demonstrate their competence or employers wishing to assure the skill of their employees can do so by gaining the relevant CSWIP Welder certification.

CSWIP Welder certification is based on qualification testing in accordance with a wide variety of UK, US, European and International Standards.

Highly experienced multi coded welders can gain recognition with a CSWIP Master Welder certificate.

All welder and brazer qualification tests are conducted to procedure specifications, which comply with relevant standards and/or client specifications.
