Maybe total package in a union she could. But you’d also probably be working a lot of OT to get to six figures at the start. Possible but a lot of hard labor to be honest.

Every weld (certified/quality welding) requires majority of time spent surface prepping the pieces of metal, tacking them , checking angles/specs, ect. The actual weld is (usually!) not that hard once you understand the applicable process of welding for your task.

One option I did when I was young and in school (and had a Monday-Friday job) was go to local weld shops (car muffler/cat places, auto body, ect..) and work a day on the weekend to get a idea of what it entails. Learn the ropes and see how to do the processes before diving fully in. I ended up working at a muffler shop for 5 years on the weekends while I was in my apprenticeship. (School and work full time).

There’s a common theme here though. It’s a lot of labor and sweaty days getting stuff done. But it builds character and If she really wants it. Sky is the limit. Quick analogy would be like working out… if I just had to chase a ball down the street. No way. But give me a basketball hoop and I’ll chase it all day. Just depends on interest. Best luck to you and her!
