About This Quiz
Practice Test FAQ
How many questions are on this CWI practice test?
This practice test has 198 questions across 18 categories covering CWI Part A topics: symbol identification, dimension reading, supplementary symbols, intermittent welds, NDE symbols, tail contents, welding processes, metallurgy, WPS and PQR, fabrication math, NDE methods, contour symbols, ISO 2553 comparison, and multiple reference lines. Questions are randomized on each attempt. Per AWS QC1:2016 §6.2.2, the real CWI Part A exam has a minimum of 150 questions with a 72 percent passing threshold. The AWS CWI Body of Knowledge (revision 2024-08) organizes Part A into 9 topic areas. Per the AWS Examination User Guide, the exam session includes 15 additional unscored pretest questions and a 135-minute time limit.
Is this the real CWI exam?
No. This is a free practice tool for educational purposes only. It is not affiliated with, endorsed by, or a substitute for the official AWS Certified Welding Inspector examination administered by the American Welding Society. The questions are original compositions verified against AWS A2.4:2020 and D1.1:2025 but are not from the official exam question bank. For complete CWI exam preparation, study the full AWS Welding Inspection Technology manual and the applicable code for your chosen endorsement.
What score do I need to pass the CWI exam?
Per AWS QC1:2016 §6.2.2, the CWI exam requires a minimum score of 72 percent on each of the three parts (Part A Fundamentals, Part B Practical, and Part C Code Application). All three parts must be passed to earn CWI certification. This practice test tracks your score against the 72 percent threshold so you can gauge your readiness. If you consistently score above 72 percent on the 18 topic categories this quiz covers, focus your remaining study time on the other Part A topic areas in the AWS CWI Body of Knowledge.
Why do questions appear in different order each time?
Questions are randomized on each attempt to simulate the unpredictability of the real exam and to prevent memorizing answer patterns. Additionally, if you retake the quiz, questions you previously answered incorrectly are weighted to appear earlier in the queue. This adaptive approach focuses your practice on weak areas, similar to spaced repetition study techniques.
