I have friends who just went on a crash course w/ Flour, used to be Flour/ Daniels, the rig workers probably know the company. He's been welding for years, he owns a muffler shop, but had no certification.
They have 3 big projects going on in the area and need welders badly. To get them, they held classes at the local tech school, the classes were free, lasted 6 weeks or so depending on how quickly you learned. He is doing mig, but his gf (who is a RN) wanted to learn tig. The tig welders are making about 40/ hr, mig about 30. You may see about something like that, they're located at the tech schools but aren't "in the school", just held there. Or I'd ask at the company office, they may can give you some more info.
Otherwise, I'll see you in a couple of weeks here in TX........ LOL
