does anyone know if the exhaust piping at autozone is galvanized?

i heard that if you weld galvanized, the fumes can kill you..

i have welded the autozone piping before, but im about to do it again this weekend.

 

i believe all the piping from autozone or pepboys is galvanized
if you do weld it make sure your in a well ventilated area
and dont sit over the part when your welding it because of the fumes and you should be fine

 

ok cool..

 

no it is aluminized. which is ok to weld. (always need ventilization when welding however)

galvanized is like the fences at little league baseball fields...also at Lowes..

yea the piping that looks like it has flakes in it?

 

yes sorry about that it is aluminized i just went to look at a piece i had from there its aluminized not galvenized
use ventilation either way though

 

nobody intelligent would make something thats made to be welded all the time galvanized...

You did not say prep the first time, I'm pretty sure aluminized can also be bad if you weld it.

Either way, there's usually copper on filler rod (or wire) and if I remember right that's even worse...

Always best to be safe and have a fan circulating air around

 

I will no longer tig any pipe that has been coated, even after cleaning them, its still no fun.

 

doesnt matter when i said it...the fact is it can be welded, regardless of what steps you need to take before hand...

same as saying anything in a wrapper can be eaten...oh you must unwrap it first

 

Grind it.
Weld it.
Drink a beer.

But a lot of people won't grind the aluminized off when they mig weld it. It just seemed like you said aluminized piping was ok to weld on, when in fact its not. If you prep it, and grind the aluminized of then it is. But then so is galvanized piping, if you prep that, and grind the galvanized off, you basically has the same pipe as the aluminized pipe.

I just wanted to make sure you need to grind the aluminized off. And drink milk a day before hand. Just in case.

 

what does milk and the coating have in common?
