Thread: Welding Stainless Steel and Aluminum

Hate to say...ran me $1400 with the foot pedal

Day 2 with the new TIG, easy to use I must say...

Im a newbie welder have about 20 hours under my belt and here is what I been able to do....

My welding setup up cost 5k all said adn done

Project P11 Intercooler Piping - G20.net - Forums

would be better off with aluminum but looks good nonetheless

I'm going to do my piping in SS too, just easier to deal with it that way. Plus it's a bit stronger .

heat dissipation is the name of the game, things heatsoak bad enough as it is, AL is the only way to go.

Aluminum picks up and releases heat faster. Thus if you have aluminum piping running outside of the engine bay it will stay cooler, but as soon as it enters the engine bay it heat soaks.

My piping is aluminum right now, I had to heat wrap the hot side that was inside the engine bay so that it wouldn't get radiant heat from the engine/turbo/manifold/exhaust. I also had to wrap the cold side to keep it cooler (once it entered the engine bay).

The reason I'm doing SS for cold side is though, I can weld it instead of using 200 silicon couplers. Plus SS dissipates heat fairly well too, but I plan on heat wrapping anything inside the engine bay anyway.

I'm thinking about welding up an air/water pretty soon, we'll see how it works out.

Tig, cuz everything else will look like shit.
