Read welds, remember the terminology, and build a steady exam-day rhythm. GaugePass is an independent study aid for people preparing for the AWS Certified Welding Inspector exam. It combines focused welding practice with an interactive gauge trainer, a structured question bank, spaced-repetition flashcards, and a practical reference library. PRACTICE READING WELDS Train the visual skills that are difficult to learn from notes alone. Work through five generated gauge modes: ⢠Fillet leg size ⢠Convexity and concavity ⢠Groove reinforcement ⢠Undercut depth ⢠Discontinuity identification Each round gives you a new weld to read and immediate feedback. STUDY 420 QUESTIONS ACROSS 9 DOMAINS Build confidence in welding processes, heat control, metallurgy, NDT, weld examination, welding math, safety, terminology, and inspector duties. Review worked explanations and focus practice on the domains that need more attention. PRACTICE UNDER THE CLOCK Use the 46-question, 60-minute simulation to develop pacing and see your results by domain. GaugePass is a study tool, not a reproduction of the official exam. REMEMBER 200 KEY TERMS Use the built-in flashcard deck with Leitner spaced repetition. Cards you know return less often; missed cards come back sooner. CARRY A PRACTICAL REFERENCE Browse 140+ focused pages covering weld symbols, filler metals, discontinuities, welding math, processes, and nondestructive testing. GaugePass does not provide certification, replace the applicable code books, or guarantee an exam result. Always verify technical decisions against the standards and documents that apply to your work. Not affiliated with or endorsed by the American Welding Society.
