Steamfitter / pipefitter
A day looks like: Welding, threading and fitting high-pressure pipe for heating, process and nuclear systems, mostly on industrial sites, with eight weeks a year in trade school, paid throughout.
What stops people: Getting into a UA Local 46 or 787 intake, or finding a non-union sponsor. Intakes open only a few times a year and are competitive.
Downside: Five years to the ticket. Industrial, refinery and nuclear sites mean travel, shutdown schedules and long stretches away from home.
Welder
A day looks like: Fabrication shops, construction, manufacturing. Skill is visible and testable, so good welders move up fast.
What stops people: Certifications (CWB tickets) matter more than the apprenticeship itself.
Downside: Fumes, heat and eye strain; wages vary hugely by sector. Pipeline and shipyard pay is high but means travel.
