What can you tell me about being a Pipefitter?

19 year old here. Friend is trying to get me into it.

What kind of pay do you start off with and what can you expect 5 years down the road if you bust arse and are competent?

I'll be working working in Louisiana and at plants. Is work here generally consistent or do you have to constantly go out of state. He said we'll being working on turnarounds.

Lastly, what kind of hours can I expect. Is 5-10s the norm or 7-10s.

I'd trying googling all this but it varied so much from state to state.
