To become an AWS Certified Welding Inspector you must pass three exams: Part A (Fundamentals), Part B (Practical) and Part C (Code Book). Here are the key facts.
Fundamentals
Closed-book theory: welding processes, metallurgy, NDT, welding symbols, safety and inspector duties.
Part A question bank →Practical
Hands-on inspection of weld replicas with measuring tools and a Book of Specifications. A strong Part A foundation makes Part B much easier.
Covered through our Part A fundamentals material.Code Book
Open-book, time-pressured questions on your chosen code — AWS D1.1 (structural) or API 1104 (pipeline). Speed finding clauses is everything.

The answer explanations made the API 1104 logic finally click for me.
The Part A fundamentals questions were spot on for what I saw on the exam.
Super easy interface on my iPad. I studied every lunch break.
The bundle was worth it — Part C practice plus Part A theory got me through.

How much does the AWS CWI exam cost?
AWS lists the initial CWI exam fee at $1,255 for AWS members and $1,520 for non-members (2026). Fees change, so confirm on the AWS website before booking.
What is the difference between AWS CWI and CSWIP 3.1?
AWS CWI is issued by the American Welding Society and is most widely recognised in the Americas. CSWIP 3.1 is issued by TWI Certification and is widely recognised in the UK, Europe, Middle East and Asia. We offer prep for both.
