The Certified Welding Supervisor (CWS) is a professional credential offered by the American Welding Society (AWS) for people who manage welding operations rather than perform or inspect the welds themselves. It is aimed at experienced welders moving into supervision, current leads and foremen responsible for welding teams, manufacturing and construction professionals overseeing welding work, welding educators broadening their credentials, and owners or managers who need tighter welding quality and code compliance. Certification requires meeting education and experience prerequisites and passing two exams: Part A (Fundamentals of Supervision) and Part B (Welding Practices & Economics), delivered by computer-based testing at Prometric exam centers. The body of knowledge is organized into 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 and leadership skills (managing teams, communication and problem solving, compliance with codes and standards). Topics on this exam: Welding Safety & Quality, Production & Cost Control, and Supervisory & Leadership Skills. The CWS study guide has 3 sections and about 1,321 words.

01

Welding Safety & Quality

This domain tests the supervisor's command of welding safety requirements and the quality system that proves a weld is fit for service. Expect questions on OSHA 29 CFR 1910.252 and AWS Z49.1 for safety, and on AWS D1.1 qualification, visual inspection, and documentation for quality.
