I want to weld brackets, racks, etc directly onto the inside of a back door. Will this burn the paint on the outside?
I just bought a Lincoln welder, gonna weld all sorts of stuff in my project... gotta learn to weld first, though...

I don't know if I'd learn on my Metris. I bought a bunch of sheet stock at Home Depot to get the feel of the center cut shears before I cut in my CRL windows.

Welding will burn the paint, and welding painted metal is generally not best practices. I would follow focus’s advice about buying some scrap metal to learn your welding basics on.

Since you are welding on the inside, I would then sand off the paint from where you are welding, weld the racks on, and then liberally cover the area with paint- or better yet, bedliner. The purpose of the interior paint is to protect the bare metal; covering it with something truly impregnable like bedliner is even better.

1. You'd probably better to drill holes and bolt, or weld to a plate and bolt it to a reinforced part of the door.
2. Take a course at a community college if you can find one. Good value.

I assume you are talking wire and not stick...nothing heavy enough in the door to stick weld. I would not do either. One thing I would worry about are the various computers onboard and the welder current. I even remove my ecu on my dirt bike when I weld, and it's antiquated.

I would get a rivnut tool and plenty of rivnuts..they are cheap, and in stall steel angle or channel and then weld off of that or bracket off it. I'm ok at welding but I would not want my welding very visible as I'm just not good enough.

Thanks everyone for your advice.
I’ll be doing no welding on any of the van surfaces. Bolting only. I will do some welding on the metal bed frame that I am fabricating out out of angle iron.

You are correct. I just bought some bolts and a used air drill. I wish that I’d bought an air drill 50 years ago.. They are great!
thanks for your response...
