How to Become a Certified Welding Inspector (CWI) — Real-World Guide from Caleb’s Corner | #QualityMatters

Welcome to the very first episode of Caleb’s Corner, part of the #QualityMatters podcast! If you’re a welder, inspector, or anyone curious about stepping into the welding inspection world, this episode is your step-by-step, real-world guide on how to become a Certified Welding Inspector (CWI).

Based on Caleb’s personal journey — from welding school to earning his CWI certification, and later moving into software development — this episode breaks down everything you need to know that most official guides don’t tell you. You’ll hear practical, boots-on-the-ground advice that will save you time, money, and frustration.

Why Become a Certified Welding Inspector?

Many welders realize early that staying on the shop floor or crawling through tight spaces forever isn’t a sustainable long-term plan. A CWI certification opens doors to inspections, NDT (non-destructive testing), and higher-paying quality roles, while building on your welding foundation.

Understand the Process (and Why It’s Hard)

Becoming a CWI isn’t easy. The AWS CWI exam is intentionally challenging, and it should be — you’re certifying yourself as an expert. Expect to study extensively in these three main areas:

  • Code Book Navigation (ex: AWS D1.1, API 1104, etc.)
  • General Welding Knowledge (safety, welding processes, NDT methods, metallurgy)
  • Practical Inspection Skills (actual weld evaluation and measurements)

The exam isn’t just about memorizing answers — it’s about learning how to read, interpret, and apply complex standards accurately. AWS intentionally mixes topics to test your comprehension, not your memory.

Choose a Solid Prep Course

The prep course is critical. Caleb highly recommends Real Educational Services (or similar reputable prep programs). These courses walk you through the code books and show you where to tab important sections. They provide practice exams that simulate the actual AWS exam format. They offer real-world tips on navigating tricky AWS wording and test traps. They help clarify differences between similar concepts like welder qualification vs procedure qualification.

Pro tip: Schedule your AWS exam as close as possible to your prep course — ideally within one week, but no longer than one month after the course, to retain fresh knowledge.

Commit to a Study Schedule

Caleb studied for 2 hours per night for about 3 months before taking the prep course, followed by focused practice right up to the exam. Plan to review every section you’re weak in (TIG welding, NDT, safety, etc.). Use your prep course study materials to guide your self-study. Focus on reading comprehension — not just memorization. Practice navigating the actual code book under time pressure.

Master Reading Comprehension

This skill is crucial. The AWS exam is designed to trip you up with fine distinctions. You need to fully read every question before attempting to answer. Pay attention to footnotes, exceptions, and definitions. Double-check whether the question refers to procedure qualification or welder qualification. Build speed while maintaining accuracy.

Tip: While reading your prep materials, pause frequently and quiz yourself: “Do I really understand this paragraph?”

Know What the Exam Looks Like

The exam consists of three parts:

  • Code Book Portion: Code-specific problem solving.
  • General Knowledge: Broad welding & inspection topics.
  • Practical Inspection: Hands-on measuring weld replicas against specs.

Even though some parts may now be virtual, the essential principles remain: you must be able to apply your knowledge — not just recite facts.

After You Pass

You’ll receive your official CWI card within a few weeks. Understand your renewal responsibilities — typically every 2 and 4 years. Stay involved in continuing education to maintain certification.

Final Words of Advice

Take the process seriously — don’t shortcut your prep. Use your prep course instructors as resources — they know the exam inside and out. Remember: the hardest part is often learning how to read the code effectively. Once certified, your options open up for future career growth: NDT, UT, software, consulting, and more.
