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.

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.

Ratings & Reviews
This update fixes and expands API 1104 and ASME IX support:
• Fixed: switching Primary Code to API 1104 or ASME IX now actually changes your quiz questions and cheat sheet — previously it still served AWS D1.1 content.
• New API 1104 and ASME IX question sets and flashcard decks.
• New API 1104 and ASME IX orientation cheat sheets, matching the AWS D1.1 one.
• Reviewed the full question bank for accuracy; Settings now shows exactly how many questions are available for your selected code.
• Fixed a Filler Metal Decoder bug that misread some electrode strength values.
• Fixed a Preheat Calculator issue with quenched & tempered (A514) steel guidance.
