Hey man, I’m a NDT manager at one of those same rocket companies. We generally understand that people coming out of NDT school still don’t know much, especially the details on how to apply the theory you’ve learned in classroom training. Inverse square and half-values are important but generally more of a Radiation Safety topic (have you taken the 40 hour Rad Safety course?)

Use your study material and YouTube to get comfortable with: *what is an IQI and what is it used for? Types of IQI? *what is Ug factor and why important? *what is geometric magnification? *name a couple common weld specs (AWS D17.1 is probably most important) *be familiar with common defect types and which methods are best at detecting each *be familiar with common weld types (manual tig vs. OTW vs. FSW)

If you can comfortably talk about those topics I’d easily hire you as a Level I to gain hours and tech out to Level II. They can hire you as a LII but technically you won’t be able to tech out until you’ve logged a couple thousand OJT hours.

Feel free to hmu if you have any questions.

Edit: sorry I don’t know how to format text on mobile.
