i have a question i have a spare gas tank and instead of denting it i was going tocut the top off and weld sum diemond plate aluminum that i was gonna dent and move the gas cap so what im getting at is can i weld steel and aluminum together? input would be cool thanks Ed

 

try to weld it with the same material as the gas tank

i had mine cut off the whole bottom because of a nasty dent, fixed the dent and then welded it no problems
there were some minor leaks but i put on some poxipol

 

yea i was just gonna do it as long as it dont leak im golden

 

the tank is steel



but just remember, when you weld a tank, it burns the coating off the inside, and will rust eventually.

Still should last a few years, but will eventually start clogging fuel filters/injectors/fuelpump, and/or get a hole back through it

 

edit: just realized that you KNOW the tank is steel..

no you can't ******* weld steel to aluminum what kind of question is that. If that was a serious question, then just forget about cutting and welding the tank all together. Making that **** look right is difficult, it isn't as easy as jessie james makes it look.
Just beat it with a hammer, bondo it, paint it, and it'll look pimpin

 

no cannot weld them together, just make sure you buy some tank sealer and seal the tank after you weld it back togther if you dont want it to rust

 

No one can weld aluminum to steel

 

with omr's god-likeness im sure he can

 

wow! seriously ? alluminium to steel

 

If anyone could,,,, yes it would be OMR

 

I've seen a couple cap relocation pics and I was wondering what to use for the new cap? I got a tank I wanna try it on but don't know what to use for a cap...n e one got a sugestion? Thanks beardo

 

chuck norris can weld steel to alum.he once welded jello to a concrete block with a used tampon string

 

They do have thin diamond plate steel that would work better but one thing to remember gas tanks can explode when welding on them.
the fumes alone in an empty tank can ignite when welding so when you can, your supposed to fill them with water to take up the extra space that fumes could be lingering.....yes an (empty) tank can explode.

 

that is y u purge them first..... cmon buddy...you know better

 

something easier is pour some dawn dish soap in there fill with water spalsh it around a couple times and it wont go boom

 

Purge them?....u mean purge the existing air out before welding?
Who said i didnt know that?.....of course you purge (blow) the air out before welding but still the fumes that remain in the pores of the metal
still (can) explode that is why filling them with water leaves no space for the fumes to ignite....you can also run a constant flow of air through the tank while welding if thats what your talking about....this will (probably) work but even though it is the easiest, not the safest....even a small amount of fumes in an enclosed space can be dangerous...but so is stunting
Ps...dont go shaken yur finger at me squido!

 

I welded one because it had a hole in it. I filled it with water and emptied it first. I let it sit overnight before reinstalling on the bike and a month later had to clean the carbs due to rust. Dent and bondo it, don't **** around welding it.

 

you bastard!!! I was thinkin bout sayin that till i read down! Lol!!

 

You hook a hose to the exhaust on a car and stick it in the tank. It takes away all the oxygen so it can't ignite. I have done this a 100 times and never had a problem.

 

Hmm...sounds good.
100 times? dang, you weld alot of tanks.
