CWS Welding study guide
CWS Welding · Work through your exam, one topic at a time.
The AWS Certified Welding Supervisor (CWS) is a professional credential from the American Welding Society that recognizes people who can manage welding operations - quality, productivity, cost, and safety - rather than perform or inspect the work themselves. It suits experienced welders moving into supervision, current leads and foremen, welding educators, and managers responsible for shop-floor welding compliance. Assessment is split into two separately administered computer-based exams, Part A (Fundamentals of Supervision) and Part B (Welding Practices & Economics), delivered at Prometric test centers. Content tracks three areas: welding safety and quality (OSHA compliance, defect prevention, inspection and testing), production and cost control (welding economics, lean principles, productivity improvement), and supervisory leadership (managing welding teams, communication and problem-solving, compliance with welding codes and standards). The CWS Welding study guide has 3 sections and about 1,099 words.
01Welding Safety & Quality: OSHA Compliance, Defect Prevention, Inspection and Testing
Welding safety in the U.S. lives in OSHA 29 CFR 1910.252 (general industry) and 1926 Subpart J (construction).

Weld cost per foot = (labor + consumables + equipment + power + overhead + rework and inspection) ÷ feet of acceptable weld. In manual processes labor dominates , often 70–85% of total cost, so anything that raises arc time per paid hour beats squeezing the consumable price.

The welding supervisor directs production and enforces compliance; the supervisor is not the inspector of their own work and cannot self-approve their own qualification test. Under AWS D1.1 and most codes the supervisor is responsible for ensuring a qualified WPS is at the point of use, that each welder holds a current performance qualification covering the process, position and thickness being welded, and that continuity is maintained - typically re-qualification is required after six months without welding under that qualification, or after a change in process, position, or thickness outside the qualified range.
