AWS Certified Welder study guide
AWS Certified Welder · Work through your exam, one topic at a time.
The AWS Certified Welder Program (CWP) is a performance-based credential. No prerequisite courses or certifications are required to attempt it, and certification provides "transferrable" credentials that you may take with you wherever you go. Rather than sitting a written exam, you demonstrate ability by welding at an Accredited Test Facility, which plays an integral part in the program. During the exam you weld using specific processes, positions, and materials, and your work is inspected to ensure it meets AWS standards. The AWS Certified Welder study guide has 4 sections and about 1,305 words.
01Specific Welding Process: SMAW, GMAW, FCAW, and GTAW Fundamentals
A candidate must be able to separate the four common arc processes by their consumable, shielding method, and typical current type. SMAW (stick) uses a flux-coated electrode that melts to form both filler and slag; the flux provides shielding gas as it burns, so no external gas cylinder is needed.

Position describes where the weld sits relative to the welder and how gravity pulls the molten puddle. In flat (1G/1F) , the work lies horizontal and the welder works from above; gravity holds the puddle in place, so the highest current and largest electrodes are practical.

Base material questions test whether a candidate can identify a metal and predict how it welds. Carbon steels weld easily; low-carbon grades are most forgiving, while higher-carbon grades need preheat and controlled cooling to avoid cracking.

The five basic joints are butt, lap, tee, corner, and edge . A butt joint with a groove is the standard for full-penetration work; a lap joint is simple but creates a crevice; a tee joint concentrates stress at the root.
