AWS QC20:2011

This specification defines the certification program of the American Welding Society for use in the Certification of Resistance Welding Technicians (CRWTs). These certifications require documentation of experience, and satisfactory completion of a written examination. The examination tests the CRWT's knowledge of welding processes, welding procedures, destructive and nondestructive tests, welding terms, definitions, symbols, reports, safety, quality assurance and responsibilities, machine setup, and other related subjects. Successful completion of all requirements constitutes the basis for awarding a certification as a Resistance Welding Technician.
