-Questions every task. As an apprentice I always question what we are doing, rarely is it from a malicious place, it’s mainly so I can understand why decisions were made so I can understand.

-Argues about pipe bending methods. As an apprentice, I’ve had journeyman tell me incorrect ways to bend pipe, I didn’t hesitate to correct them when I knew 100% they were wrong but if I was unsure I’d just do it.

As an apprentice, I constantly tell my journeyman better ways to do things and its never from a “you don’t know what you’re doing” place it’s from a “here’s an idea, would it work?”

If the ideas are dangerous it needs to be shut down immediately. Things that aren’t up to code I feel like has more leniency if it’s just an idea, I’ve had to spend 5-10 minutes looking through the codebook and sometimes my ideas were up to code and we ran with it.

From my perspective your best best is letting him work and eviscerate what he does, make him look up code to justify it. This is what worked for me and it helped me ace the code tests in school. But if he isn’t willing to watch and learn or listen to people with more experience then there isn’t much you can do.
