Switch codes in Settings and watch your content update instantly. CWI WELDING EXAM PREP: PASS ALL THREE PARTS OF THE AWS CWI EXAM The CWI exam has a 30 percent first-attempt pass rate. Most candidates fail because they treat it as a single test. It is three separate exams — Part A (Fundamentals), Part B (Practical), and Part C (Code Book) — each requiring different preparation. This app is built around all three. WELD SYMBOL DECODER Weld symbols are tested heavily on Part A and appear throughout Part C. This tool lets you build any symbol and get an instant plain-English interpretation based on AWS A2.4. Select your weld type: fillet, groove (V, bevel, U, J, square), plug, slot, spot, seam, surfacing. Choose position: arrow side, other side, both sides. Add supplementary symbols: field weld, weld all around, melt-through. Set contour and finishing requirements. Get the decoded meaning instantly. The same symbols you will interpret on blueprints every day on the job. Source: AWS A2.4 Standard Symbols for Welding, Brazing, and Nondestructive Examination — https://www.aws.org/standards DISCONTINUITY REFERENCE Identifying and classifying weld discontinuities is the core of Part B. This reference covers every discontinuity type. Covered: porosity, slag inclusion, incomplete fusion, incomplete joint penetration, undercut, overlap, cracks (longitudinal, transverse, crater), arc strikes, underfill, laminations. For each: visual description, probable causes, prevention, and AWS D1.1 acceptance criteria for both prequalified and qualified welds. Source: AWS D1.1 Structural Welding Code — https://www.aws.org/standards 490+ PRACTICE QUESTIONS Part A — Fundamentals (150 questions on actual exam): Welding processes: SMAW, GMAW, GTAW, FCAW, SAW — parameters, applications, limitations. Welding metallurgy: heat-affected zones, preheat, interpass temperature, post-weld heat treatment. Weld symbols: AWS A2.4 interpretation, construction, and supplementary symbols. Welding terminology: AWS A3.0 standard terms and definitions. NDT methods: VT, PT, MT, RT, UT — capabilities, limitations, applications. Welding safety: fire watch, PPE, fumes, electrical hazards, confined space. Part B — Practical (50 questions on actual exam): Visual inspection procedure and sequence. Discontinuity identification from descriptions and specifications. Measurement: fillet weld gauges, undercut depth, reinforcement, throat. Acceptance criteria application: when to accept, when to reject. Part C — Code Book (50 questions on actual exam): AWS D1.1 Structural Welding Code: general requirements, design, prequalification, qualification, fabrication, inspection. WPS (Welding Procedure Specification): required variables, essential variables, format. PQR (Procedure Qualification Record): test required, acceptance, documentation. Welder qualification: positions, test weld types, retesting requirements. Code navigation: finding the right clause under exam time pressure.
