The navy has been a great career opportunity, I will say it depends on what you are looking to do with your welding skills. The navy has HT's(hull technicians) who weld but that is not their only job. As well as you are not guaranteed to get that school enroute to your first command. Joining the navy to do a specific task is usually a difficult challenge, you can always get close but just know nothing is guaranteed. On top of that, if you do get the job you want and the school to be able to weld and hold that position on the ship you also have to deal with a lot of other things to, maintaining your fitness, collateral duties, volunteering, outside education, other tasks with in the command. What you have to ask yourself is whether or not you want to weld for the navy and if you do you need to talk to a recruiter and research and look up everything they say. To verify you are keep in control of your future.
