I want to get into welding so that I can work in remote areas and or on a boat. What certifications and otherwise skills would I need to do that?

I've been to Alaska before trying to work on a boat, but those guys are all drug addicts. Unknowingly hired my own replacement after a few weeks. I have no friends, no family. I have two grand but can get more money if needed, and I have all the time in the world because I'm sleeping in my truck. The ultimate goal would likely be to end up in Alaska, permanently. I'm in my late 20s. Is this reasonable?
