re: Will be a boilermaker helper. Would like some tips/advice and what I'll be doing.

Good attitude and work ethic goes a long way. Listen more than you talk. You’re there to learn. Play by the rules. Ask questions. You can be pushing a crew with a double radio holster and company truck in no time. Turning wrenches and shocking winches.
In all seriousness it’s a great field and we need more crafts wanting to learn it. Make the best of the opportunity my man.
