Pinch Weld Question *ADDED PICS*

Well, ive been looking at alot of build threads where people did the pinch weld. noticed that everyone strattles the weld spots and just knocks the weld over. well i grinded straight through the welds and took the metal from the pinch weld as far back as possible without knocking it over. so there is no more weld spots now.

my question is will it eventually start to mess up later on down the road? like since i cut the welds off will it start to split? and is there any way to fix it if so?

Im a 19 year old college guy who tying to learn! lol

please no negativity. thanks!

A pinch weld is the location where current is passed through the metal(literally pinched), it becomes liquid, cools then is one solid piece. When you grind this spot weld away, normally the manufacturer will use a chemical bond to help that weld and seal it but the chemical wont hold the metal. This probably wasn't the best idea but good luck.

I'm a little confused. Got pics?

Are you saying you just cut the entire pinch weld out instead of folding it over? I hope not. There is a reason people are making their cuts between the spot welds.

From what I understand of your method - yes, it will eventually split because you eliminated the welds holding the seam together. And, if this is the case you will need to get some flat stock steel, or strap that is wide enough, and weld it into what's left of the seam.

Well, my stepdad can. he is the one that cut the weld off to begin with. just need to know if i can fix it and be ok in the future, or would i be better off selling it and getting another WK to do it right next time?

I'm purely guessing here- but my mechanical engineering degree tells me that running a weld bead (properly) down the seam would restore the electrical flow properties as well as restore (most) of the integrity of the body assembly. I would think this is what a dealership will want to do as well, after they give up on trying to convince you to actually replace the front clip and associated body panels... I would say run a weld down it and go from there. There is WAY more involved that creates the strength and join those body panels than just the pinch weld... I wouldn't be super worried about it after it was rewelded.

You do realize that if you just weld it. And have an accident and you or someone is killed your getting a big big lawsuit. This is the integrity of the car. No bashing his did body work for transcend this is quite important

I would re-weld the seam. The welds are there to help keep the pieces together so eliminating them is not a good idea.

It won't but if that Sean is designed to absorb a force and it can't take that same amount of impact more will be transfer to you and passengers. They look for stuff like this is all I'm saying.
