PassCWI provides practice material to help candidates prepare for the AWS Certified Welding Inspector (CWI) examination, with an emphasis on the Part B practical. It is a study aid only. It is not the AWS exam, is not a substitute for AWS D1.1 or any AWS standard or seminar, and does not certify or qualify anyone. We make no guarantee of a passing result or any particular exam outcome. Always rely on the current edition of the applicable AWS code and the official AWS exam body of knowledge as your authority.
Specimen calls, measurements, and reasoning are original works created by PassCWI. Material marked "draft" or "pending CWI review" has not yet been verified by a credentialed Certified Welding Inspector and is shown for practice only — do not treat it as exam-authoritative until that notice is removed. We reference AWS acceptance criteria by citation only; we do not reproduce AWS code text or AWS exam specimens. If you believe a call is wrong, email us — see Contact.
If you choose to enter your email address, we collect that address (and, if present, the campaign/source parameters in the link you arrived through) to send you study material and product updates. Email is stored and sent through our email provider, Kit (ConvertKit). We do not sell your information. You can unsubscribe at any time using the link in any email, or by emailing us.
The simulator is free. Paid products (such as the Part B Specimen Field Guide) are sold through our payment processor and carry the refund terms stated at checkout. If a paid item contains an error in a verified call, contact us for a correction or refund.
PassCWI is provided "as is," without warranties of any kind. To the maximum extent permitted by law, PassCWI and its owner are not liable for any loss arising from use of the material, including exam results or decisions made in reliance on it. Inspection of real welds must be performed by qualified personnel against the governing code — never on the basis of this study aid.
