You should jump on it. Check out the company on the internet to make sure they are on the up and up.
Companies are feeling the pain of Welder shortages.  They are going to great lengths to promote and lure folks into the welding world.  This will also give you an idea if you will enjoy welding full time and give you time to think about recruitment into the armed forces.

Yes, no doubt about it, jump all over it.
Combo hands (fit and weld) get hired before others, remain on site when others get laid off, and can get paid more.

Never turn down an opportunity to learn something new. Even if you never become a fitter, the knowledge is transferable to other related fields. Hell, you might even learn how to read a measuring tape, layout a miter, and so much more.

Knowing how to weld is important, but so is learning how to use equipment and tools used in industry.

I agree with the others...take every opportunity that is offered. Knowledge...hard to put a price on that.
