Learn the reasoning behind every answer
The CWI exam rewards inspectors who can read a symbol, apply a clause and judge a weld against the criteria. Every explanation works through the rule or calculation behind the answer, so you learn why, not just what.
- Original questions written to the AWS content areas for each part
- Trap answers called out, like confusing undercut with underfill
- Practice by topic or mixed, with instant feedback
See your weak spots before the exam does
Your Readiness Score day by day, accuracy by topic with the weakest first, and every timed mock exam against the pass line. One click on a topic starts a drill on it.
- Topic accuracy updates after every question
- Mock exam scores plotted against your target line
- The Today list sends you to your weakest topic first
Remember it on exam day, not just tonight
Spaced repetition brings each card back right before you'd forget it. Cards you miss return in 10 minutes. Cards you know wait days or weeks.
- Terms, symbols, values and formulas that get tested
- 15 new cards a day, so reviews never pile up
- Mastery feeds straight into your Readiness Score
Turn every missed question into a point
Every question you get wrong is saved with its explanation. It only clears after you get it right twice in a row, so lucky guesses don't count.
- Re-test all your mistakes in one click
- See the right answer and the rule behind it
- Shows how many you've cleared, to keep you going
Walk in having done it before
Timed mocks with no feedback until you submit, the way exam day works. Part A gives you just under 50 seconds a question, so pacing matters.
- Part A pace: 165 questions in 135 minutes
- Quick 25-question mocks for a lunch break
- Two full simulations count toward the Pass Guarantee

Are these real exam questions?
No one can legally sell the actual exam questions. Ours are original questions written to match the AWS B5.1 content areas, the free Part B Book of Specifications and the D1.1 code, with an explanation for every answer and the clause or calculation behind it, so you can check our work.
Is the content up to date?
We check each exam page against the current AWS CWI page, program price list, Examination User Guide and Exam References and Editions Guide, and show the date it was last checked. In 2026 that included the US$1,255 member / US$1,520 non-member exam fee, the 72% pass mark on each part, and the D1.1/D1.1M:2025 edition listed in the 20 Oct 2026 references guide.
Do I still need the code book and the Book of Specifications?
Yes. Part C is open book, so you need the code you chose, and Part B is answered from the AWS Book of Specifications, which AWS provides free to download and supplies on exam day. We're the extra practice: more questions, timed mock exams, flashcards and a Readiness Score so you know when you're ready.
Are you affiliated with AWS?
No. CWIQuizBank is an independent exam-prep company, not affiliated with or endorsed by the American Welding Society or Prometric. AWS, American Welding Society, CWI and Certified Welding Inspector are marks of the American Welding Society, used only to describe the exam we help you prepare for.
