Thread: Clean a pan before welding

Tweet

I just got a decent deal on a 200-4R transmission that I plan to use in my 54 Stude wagon. Part of the reason I got a good deal is the pan has a small crack in it that I believe I can weld to repair. Looking for suggestions on getting it clean and oil free so I can make a good weld. I plan to use my MIG welder.

thanks

Gasoline. Make sure It's dry before you weld.

I have used brake clean then a torch to heat it to get all residue off the metal

Actually having read the article linked below I know that brake clean and welding do not mix. That's why I was asking for suggestions. Read this article, I think we have discussed it here before.

I WOULD STRONGLY RECOMMEND NOT USING BRAKE CLEANER.

Charlie's method would probably get rid of the residue, but I wouldn't take the chance.

It's been a while since this has been posted so it's probably worth doing again.

EDIT: Looks like you beat me to it Stu.

dawn soap and water.

The Posgene gas is produced by Tri Cloretheline being heated. That cemical is no longer used in brake clean... Shine's recomendation will work just fine

Seems to me that a torch would burn out anything but the parent metal and leave you good to go, but then, I've never welded on a pan.

pans is what steel or aluminum welded ? i would not use a mig for alum .if its steel just wash with thinner is all is needed i cross the ends of the crack with to small welds going across the cracks on the ends if alum drill the ends of the crack then v groove the part do not use soap some soaps need to be cleaned out not a big deal on steel but cast can be porous so just use thinner and a stainless steel brush i only would TIG it pre heat would be a very good idea to about 300 if a small tig or mig if your going to try to weld it if aluminum

Wiping it first with lacquer thinner and then soap and water then blowing it dry. I would then use some 00 steel wool . You haven't said what the pan is made of, steel or aluminum. If it's steel it may have a coating on it that will need to be removed before welding and that will require more than steel wool.

Might be a good time to consider a deep aftermarket pan for it.

You think like I do Gary. Pans aren't that expensive.

Thanks everyone, it is a steel pan. Given the use planned for this car, the stock pan should be more than adequate.
