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.

MONTHLY ($9.99/month): Full 490+ question bank, complete Weld Symbol Decoder, Discontinuity Reference, D1.1 Code Navigator, progress tracking by exam part, 3-day free trial.

Verdict
The clearest difference is rating: CWI Welding Exam Prep at 4.4 against Weld's 4.2. Weld's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ratings volume, update cadence and ads there is nothing between them.
