CWS (ABWM) study guide
CWS · Work through your exam, one topic at a time.
The Certified Welding Supervisor (CWS) is a professional credential listed by the American Welding Society (AWS) alongside its inspector, educator, engineer, and welder certifications. It is aimed at people who direct welding operations - lead welders, foremen, shop supervisors, and production or quality staff moving into supervision - rather than at individuals whose main job is to inspect or to weld. AWS also lists Welding Supervisor as a distinct career path in its careers-in-welding resources, which reflects the role's blend of technical, personnel, and documentation duties. Because a supervisor's work spans people, process, and paperwork, preparation usually covers four areas: supervising and managing a welding operation; welding processes, procedure and performance qualification; quality assurance, inspection, and code compliance; and safety, productivity, and cost control. The CWS study guide has 4 sections and about 1,222 words.
01Welding Supervision and Management
A Certified Welding Supervisor is accountable for the welding operation, not simply for welding. That means planning the work, matching qualified people and approved procedures to each joint, and proving it with records.
328 words, about 2 min02Welding Processes, Procedures, and Qualification
Learn the chain cold: PQR → WPS → welder performance qualification. The PQR is a record of a test that proved a procedure; the WPS is the production instruction written from it; the performance qualification proves the individual.

Inspection runs in a hierarchy: visual first, then surface NDE (PT or MT), then volumetric NDE (UT or RT). But inspection starts before the arc - verify WPS availability at the point of use, consumable certificates, joint preparation and fit-up, preheat, welder qualification records, and equipment calibration.

Under OSHA 1910.252, hot work needs a permit where required, a fire watch where combustibles are exposed within 35 ft, and the fire watch must continue for 30 minutes after welding stops. Ventilation must control fume; confined spaces need atmospheric testing and an attendant.
