Essential concepts for the Certified Welding Inspector exam

📚 🏗️What does the welding symbol flag indicate?

The flag indicates a field weld, meaning the weld is to be performed on-site rather than in the shop.

🎯 🔥What is the primary cause of porosity?

Porosity is typically caused by trapped gas in the weld pool, often due to moisture, contamination, or improper shielding gas coverage.

💡 📏What is a V-WAC gauge used for?

A V-WAC gauge is used to measure undercut depth, crown height, porosity checks, and pit depth comparison.

📚 📘What does AWS D1.1 cover?

AWS D1.1 covers the Structural Welding Code for Steel, one of the primary codes tested in the CWI exam.

🎯 ⚠️What is arc flash?

Arc flash is a painful eye condition caused by exposure to ultraviolet (UV) rays from the welding arc without proper eye protection.

CWI Questions and Answers

How many questions are on the CWI exam?

The CWI exam contains 150 multiple-choice questions in Part A (fundamentals) and 46 questions in Part B (practical application using the Book of Specifications). Part C, the code book portion, has 46-60 questions depending on the code chosen, such as AWS D1.1, API 1104, or ASME Section IX.

How long does the CWI exam take to complete?

The full CWI exam is administered over approximately 7 hours, with each of the three parts allotted 2 hours. Part A covers welding fundamentals, Part B is hands-on practical inspection, and Part C tests code book navigation and application within the selected code.

How do I register for the AWS CWI exam?

Registration is handled through the American Welding Society at aws.org. Candidates submit an application with work experience documentation, education verification, and a vision test signed by a licensed examiner. The exam fee is $1,150 for AWS members and $1,385 for non-members as of 2026.

What work experience is required to sit for the CWI exam?

AWS requires a combination of education and welding-related work experience. For example, candidates with a high school diploma need 5 years of experience, while those with an associate degree in welding technology need only 2 years. Experience must involve welding processes, fabrication, inspection, or quality control.

What topics appear on Part A of the CWI exam?

Part A covers welding fundamentals including welding processes (SMAW, GMAW, GTAW, FCAW), metallurgy, weld joint geometry, welding symbols, destructive and nondestructive testing methods, weld discontinuities, safety, and inspection principles. It is a closed-book test requiring memorization of core welding inspection concepts.

What is the best way to prepare for the CWI exam?

Most candidates take the AWS Certified Welding Inspector Seminar, a 1-week preparation course offered before each exam. Study the AWS B5.1 standard, review welding symbols per AWS A2.4, and practice with the specific code book you will test on. Taking timed practice tests helps build the speed needed for Part C.

How often must CWI certification be renewed?

CWI certification must be renewed every 3 years through a simple renewal application and fee payment. Full recertification is required every 9 years, which involves either retaking the exam or completing 80 hours of continuing education in welding-related topics through AWS-approved courses.

Which code book should I choose for Part C of the CWI exam?

Candidates select one code based on their industry: AWS D1.1 Structural Welding Code (steel construction), API 1104 (pipelines), ASME Section IX (pressure vessels and boilers), or AWS D1.5 (bridges). Choose the code you use at work, since Part C tests your ability to quickly locate specific clauses under time pressure.
