Can "aluminized" tubing be welded?

Can this tubing from Summit be welded? http://store.summitracing.com/partde...5&autoview=sku

As best I can make out, it is an aluminum coating which is applied to the steel tubing. Could it be welded "as it" or can this coating be easily sanded off for proper welding.

I can get the tubing I want elsewhere, but I'm putting in an order at Summit anyhow so I could save the shipping cost by getting this in my Summit order.

welding aluminzed tubing

After you welded it, can you coat it with something to return the aluminumization to the joint ?

If you're just looking for rust protection, I've used rattle can Zink coating. I picked mine up at Lowes.

You should be able to weld any metal you can stick a magnet too. (After cleaning it off.)

At the muffler shop next door the guys just weld through it. It welds just like bare steel. I wouldn't grind it, as that would make a wider area of bare steel for rust to start.


Later, mikey

Muffler shops just weld right through it then spray some cold galvanizing compound on the joint to keep it from rusting.
