welding /replacement lower panels

Post by 79izfine » Mon Dec 08, 2008 6:26 pm

what i am wondering as i am a novice in this area well i have extra quater panels i wanted to use as a template to form lower panels behind the rear tires what stumps me is how to create a lip that would seat inside the quater panel creating a backing to weld the seam and have the cut/seam to be flush ,was also going to drill holes in the outer portion {like a spot weld } and weld the inside lip of replacement panel to the outer original panel . so my quest ----- is there a tool to do this ? another ques what gauge is thick enough ? what i intend to use for a welder is a wire feed non gas mig and it only has a min/max amp setting and running .030 flux core wire hope it makes sense thanks

I think your talking about a flange tool. Don't know much about em. Here's a quick link. Is this what your trying to do? I just grabbed the first thing off a google search. There is pneumatic ones too.

one problem with flanging them is now water could get in between the two panels and form more rust.

18 guage steel will work fine

I can almost guarantee you that you will blow holes in your sheet metal not using gas. If you insist on using flux practice on scrap first.

With glue it will seal the panel were you were going to weld and it will hold as good and maby better than you would thank. I have seen this used in alot of applications. And so far so good. I used to do alot of body work my self but iam not a pro.

i saw them use that on the powerblock trucks a member here used it also i am going to try the welding if that fails i will go the adhesive route but wont be doing anything until spring would eastwood have that adhesive? i figured with a flange there would be a better chance not having blow through with the welder think i will do research thanks

Yeah i would go the welding route if i had on. I am just now building up what i used to have. The best thing is the glue will seal/fuse the two pieces of metal together. Other than using the welder you must use weld through primer and if at all possible paint the back side of the metal to seal the air and water out also dirt from getting in. Rust sucks.

oh i hear you on the rust i have alot of rust/rot what i was planning was drilling spot weld hols along the flange then prime and paint the mating surfaces then setting the panel on and tracing the spot weld hols then cleaning the paint on the trace marks then welding the holes a bit extreme but the paint will help the sealing bare metal i did this when i remove my wiper tray to clean and paint up under it and it welded fine .

Like some the guys here said: There are various brands of body panel adhesives that work very well. One other way you can create a backing to weld to is cut a strip of 16-18 ga. metal, drill a couple holes and plug weld the backing strip (which would be partially inserted behind existing quarter panel) Then you could use the adhesive to attach the patch section to your backing strip. Flux core welding will be somewhat tricky to do and should be avoided. Gas Mig is a much better process to use if you are able to. The flanging tools are OK at best and have a tendency to create unnecessary waves in the metal.

You can also use weld thru primer, won't melt like normal primer or paint & is corrosion resistant.
