Welding (in Michigan) starts at 20/hr. Goes up from there. Can hit (if you're decent) up around 60/hr. 

At 40hr work weeks, 124,800 gross, take home around 90,000. 

Plumbers charge 60+/hr, electricians in the indiana/michigan area charge close to 75/hr. Blue collar work pays well if you're willing to be working hard and diligent.
