New CWI? Here's What Nobody Tells You About Welding Inspection w/ Daryl Peterson
Wednesday, 11 March, 2026

Passing the CWI exam is a huge accomplishment — but it's only the beginning. In this episode of the Arc Junkies Podcast, Jason Becker sits down with veteran welding inspector Daryl Peterson to discuss what new Certified Welding Inspectors really need to know after earning their certification. From ethics and inspection authority to metallurgy, code interpretation, and non-destructive testing, this conversation breaks down the real challenges that many new CWIs face when they step into the role for the first time. Daryl shares insights from 40 years in welding inspection, including the importance of mentorship, understanding QA vs QC responsibilities, and why gaining experience in NDT methods like PT, MT, UT, and radiography can dramatically improve your effectiveness as an inspector. They also discuss common industry myths, welding metallurgy concepts that inspectors must understand, and how unethical decisions early in your career can have serious consequences. If you're a welder thinking about becoming a CWI — or a newly certified inspector trying to figure out your next move — this episode is packed with practical advice from someone who's spent decades in the field. Topics include: What new CWIs should focus on after passing the exam The difference between QA and QC inspectors Why ethics and integrity matter in inspection How NDT experience can accelerate your career The metallurgy concepts inspectors must understand Common welding myths and misunderstandings
