filling trim hole - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i was filling my trim hole and i got burn through, turned the welder down as far as i could and still get penetration and i still got burn though. so kept tacking and letting cool and i finally got it all welded up. its about an 1 1/2" x 1" should i leave it or cut it out and put in a patch. also i could get to back one to hold a piece of copper to it so i just used multiple tacks to fill. is this ok.

Metal is metal, so if you've already smoothed it out with a grinder and it's welded solid, with no pinholes, then I would leave it.

Mike, maybe the area you are welding is real thin with dirt/ crap on the back side? imo, the metal should be cleaned (both sides) I'm just sayin my .02 hope this helps you. Pat

What helps me when filling holes is to use some magnets to hold a piece of copper on the backside of the hole.

Yes it will fill pin holes, but it doesn't resist moisture very well at all. Been there, done that, lol.
