How to pass the AWS CWI Exams

Passing the AWS Certified Welding Inspector (CWI) exam requires thorough preparation and understanding of welding processes, codes, standards, and inspection techniques. Here’s a step-by-step guide to help you prepare effectively:

Understanding the Exam Structure: Familiarize yourself with the exam format, duration, and topics covered. The CWI exams consists of three parts: fundamental knowledge, practical applications, and code application. Practice computerized exams that will get you familiar with the AWS and Prometric exam systems. Read the publications that cover these topics. i.e. AWS QC1.

Gain Practical Experience: Hands-on experience in welding and inspection is crucial. Spend time working in the field to understand various welding processes, equipment, and techniques. If you lack the experience you can take a hands-on type visual inspection course/workshop.

Study Welding Fundamentals: Review basic welding principles, including metallurgy, welding processes, welding symbols, and welding defects. Understand the properties of different metals and alloys. These subjects are covered fully in our Part A Welding Fundamentals Classroom or Online Course.

Learn Inspection Techniques: Study different inspection methods such as visual inspection, radiographic testing, ultrasonic testing, magnetic particle testing, and dye penetrant testing. Understand how to interpret inspection results and identify defects. Nothing beats hands on practical experience.

Review the Code and Standards of your choice: Familiarize yourself with the relevant codes and standards, such as AWS D1.1, AWS D1.5, AWS D1.6, ASME Section IX, and API 1104. Understand the requirements for welding procedure specifications (WPS) and welding performance qualifications (WPQ).
