Actually it does since those pinch welds are 2 of the strongest points of the body.With those compromised that area will crush when it's not supposed to since it's the beginning of the passenger compartment.

Oh ok... I think it's slot of here-say .. before doing it I got tired of searching on the web any pinch weld failures , i don't think there's any measurable differences in crashes vs cut and welded pinch weld ... has any of the people who are against it have actually done it and seen it fail ?? or if anyone has some actual prof it does make a big difference I'd like to see the article ....

Ok I think Tommudd will have a stroke if I cut it more so I'll leave it alone. Whether I like it or not half of my pinch weld is gone. I just gonna pound what's left and seal. Should I try to do any welding to strengthen what's left? Maybe I'll just buy new fender liners. I'm still gonna have to lift up to 4" if I want to run the 32s.

Yeah definitely Weld something to it. What I did is I welded the seams back together then welded a plate all over it. I went with eighth of an inch metal... I think there would be more problems going four-inch or taller. Versus just cutting and welding the pinch weld to run the tires.

I don't feel comfortable cutting any more off. I'm just gonna pound whats left over to the side. I'm just wondering if I should weld whats left of the seams back together or add any extra steel. Obviously adding too much defeats the purpose of trying to gain more clearance. I'm not convinced pounding with be enough clearance for the wheels to flex so I think either way I might have to raise to 4".

Go work at a body shop and become the frame machine guy,you'll learn all about what I'm saying.

How about you actually learn about unibody construction,crush zones, and repair before you dismiss anything.Just because you can't find it on the internet does not mean it's not true.All you will find is unibody vs body on frame discussions.

Not here say at all, take yours to a good quality body shop and asked them if you don't believe us
COMMON sense as well
I've also been in the Jeep plant and say KKs being built, actaully discussed this with one of the tech guys in there about what some were doing
Won't type out what he said , but wasn't good

I am sure it does compromise crush zone etc but i bought mine already ground off totally. I did know it before i bought it but got great deal. It clears the wrangler takeoffs that r 32.1 inches barely with a 2 or at most 2 !/2 lift daystar front about same lift as my sons old man emu lift in front.

How would it be possible to more or less recreate the crimp toward the interior passenger compartment side rather than the exterior wheel side ?

It seems like this may be doable though a lot of work.

Guys do I need to weld what's left of the seams back together and/or weld extra steel to reinforce my pinchwelds? I'm wondering if adding extra steel would make it easier to pound the whole thing over.

You could run a bead down the seam and pound it over. Doesn't look like it was pounded flat at all.

Zip a coat all the way up, then try and pull the two sides of the zipper, nothing much will happen. Now undo the zipper a bit and try again, the zipper will fly open. That joint is where the body side outer, inner, reinforcements, and underbody tie together. Would you ever notice during normal use? Probably not, but in an offset collision, or even worse, a narrow offset, the body side (and doors with it) will zip away from the underbody instead of crumple.

So seems I can rehab it a little with some welding? Tips on a decent welding kit for a beginner?

For this, please take it to a pro.

For learning to weld, get a setup you can afford and practice on things that the life/health/safety of you, and everyone around you, don't depend on. Bits and pieces of scrap metal work well.
You can work with assorted thicknesses, and metal types. Learn what works, what doesn't.

I learned first with stick welding with an old AC welder.
Once I got into high school shop, I got experience with dc and oxy/acetylene.
MIG and TIG came later.
Even at that, I would still take it to a pro. Not that I don't have confidence with my abilities, but I know I am an amateur.
I have enough experience, and knowledge to know better than trust my life and everyone around me to my abilities as a welder.

Do you think its necessary to repair my pinchweld?

Professional please, not only can you really screw it up not knowing what you are doing but you do know what is right on the other side of that right?

If it were mine, I would.

The price is nearly insignificant compared to the potential costs of repair to your Libby, your body, and many other unforseen things.

ALSO it's likely that IF anything happens that involves an insurance inspection, I can guarantee that if you read through your insurance policy book in detail, there is something in there covering safety features being disabled, which lets them off the hook, and you will be on the hook for everything, and all costs. And yes, pinchwelds in a unibody or hybrid-body structure (crumple zone protection) are safety features.

It doesn't seem that hard to just run a bead down the seam to seal it, and then pound it over. I don't see what a professional would do differently that I couldn't learn how to do. I really can't afford any more labor costs if there's any chance I can do it myself. I bought a flux core welding unit and I plan on doing a bunch of practice welds on sheet metal. I realize the MIG units with shielding gas is better but I would have to weld outside in my driveway. I'm a quick learner. Feel free to convince me otherwise though.

tjkj2002 · **Posted:** Thu Jun 15, 2017 1:09 pm

Flux cored wire is not a good choice for automotive applications,very messy and must be cleaned very well if you plan on coating the weld with anything.

Plus your average 110v-120v flux welder is not powerful enough for any structural welding,you need to step up to 230v.

And the issue with welding in that area has to do with seam sealer and automotive foam which will catch fire very easily.Don't want to start your interior on fire and you will need a surge protector clamped to the battery,Goodall makes a good one(part#GDL32020).
