re: I want to learn to weld..

To OP, you can see from responses that welding is (maybe like most things) on two different levels.

I’ll differentiate by saying household or farm welding versus professional welding.

The Bama hwy poster is cream of the crop. It’s extremely difficult to weld round pipe and have it pass inspection.

You can build a bbq grill though and that’s a great first project.
I’d invite you to watch videos of pipe welding, it’s amazing.

Kudos again to hwy Bama
