If you are interested in doing field work or building erection you could look into ironworker or pipefitter unions and ask about apprenticeship programs.
Most shop jobs doing structural or railing work will offer variation in your day allowing you to learn many important skills for welding such as layout work, finishing work, and in some cases design work.
Look for a local shop that is open to training and has opportunities to grow and learn new positions.
Pick up as many skills and welding applications as you can. Don't become a one-trick pony. Maybe you're only interested in welding now but as you gain experience in different environments you may decide you want to apply those skills to being something such as a maintenance technician, an auto body technician, an NDT inspector, etc. Give 100% on every opportunity that comes your way; you never know when you'll find something you have a true passion and aptitude for. Good luck
Dont forget about the weld test.
Do some research and learn all you can about the company's products and services.
A mig welding job in a shop base environment can be a quick way to start building fabrication and welding skills.
I have worked in residential, commercial, and shop welding environments.
Its all about what you want.
After your experiences you are now a more experienced welder.
You can master your work there and grow confident taking on a new and challenging traveling job for more growth afterwords.
