Alloy Welding


Recommended Posts

Anyone know who can weld alloy, i need a nut welded for a sensor in one of my intercooler pipes but they are made of alloy

I also need the nut (don't know the size) so is there anywhere that has a good range of nuts (no silly comments pls lol)

Are you sure they are alloy?

My DR725 pipes were stainless. I hasd to tap one for the water injection.

www.stagonset (im sure that is the name) is where I got all my stailess fixings for the seven.

But if your pipes are alloy, you need an ally nut or lump that can be drilled and tapped.

I'm sure it's alloy as a magnet won't stick to it?, think you had the polished pipes on yours where the new kits have red pipes that match the STi inlet manifold

Alu will scratch with a finger nail and stainless is none magnetic aswell.If your after alu welding its Tig welding you won't very neat and tidy compared to Mig with alu wire

OK thanks for that, thought stainless would be magnetic as well :boldblue:

Looks like it could be stainless then as it didn't scratch :P

Only austenitic stainless is non magnetic, and it is dependent on the level of chromium and if it contains nickel. Most stainless will be magnetic. You could always measure the density.

Yes, the 300 series contains nickel and is not magnetic unless it has been cold beaten and reletively thin. Which a nut wont be. Pop it in a jug of water!

My bet is its either of those 2 stainless steels i mentioned earlier. Would i be right in thinking that the thread will probly be a BSPF (british standard pipe thread)?

Lmao B) sod off!!! :thumbup::thumbup:

I only know a bit about metals because I work in plastics and more people want engineering polymers over metal so we need to know what they were previously using.
