Joshua,
Sorry about the slow response, the internet hasn't been working offshore. It really doesn't matter which dive school that you attend, you will have to go thru the dive company's welding program. Having gone thru the program at the college of oceaneering back in 96/97 thought that it would help. What I realized after getting to the point where I was teaching the welding class was that the guys that didn't go thru any type of training picked up the wet welding faster. The guys that knew how to weld picked up the hyperbaric welding faster. There are a raft of dive schools out there, if finances are a concern I would lean heavyly to Young's Memeroial out of Morgan City La.. As far as pay is concerned, that will depend on your skill level and the company that you work for. Some company's you hash out a contract before the weld and agree on your pay. Some companies have a flat rate of increase over your dive rate, i.e. add $5 p/h, others have an actual welding rate.
