Customer Project: Cast Iron to Stainless TIG welding

[Kevin Doe]

Just an example of my TIG welding services. PM me if you need something TIG welded. Steel, Stainless, Cast Iron, Aluminum, Cast Aluminum, Titanium, etc, I can do it all. Obviously it still needs a hole drilled into it.

Also could use some ceramic coating. Wink wink

That is bad ass. I really did not even know you could weld stainless to cast iron.

[Buckeye]

Keven you want to weld up a upper intake for a 2.3 ford?

[Kevin Doe]

Yeah Kenny, you should solicit him on CSS, its Pirhana Matt.

Sure thing, I assume you want to rotate it and weld it back up?

[Buckeye]

Yes or use the flange and weld a 3in elbow and a flat plate I can drill for a larger throttle body

[Kevin Doe]

I'd think you'd need a bit more than a 3" elbow, but its been a while since I've seen a stock 2.3T stock intake manifold.

[Buckeye]

Well pm me what you think it will cost to rotate and weld 90 degrees and then we can talk taking it up a notch when I bring it out.
( I really want a front facing mailbox style intake ideally )

[Kevin Doe]

I'm honestly not really that interested in doing much fab work. I don't have a whole lot of time to do that sort of stuff anymore. I can do welding though, since the time involved isn't a ton. I usually like people to get all the work done, and ready to weld, then bring to me for welding. To weld something like a cast aluminum manifold, prep the weld area (clean and groove out) and weld around the circumference of it, probably in the range of $50.

[Buckeye]

Ok I can cut the pieces and and get it ready then just have use blaze it together

Good looking work, Did you pre-heat it first or just go to town? I can Tig stainless, mild and aluminum but when it comes to castings the fit hits the shan. Ductile and Gray Iron always seems to haunt me:(.

Preheat it as much as possible. I used a MAP gas torch for ~5-7 minutes before I started. It was pretty hot. Then when I start the arc, I roll the heat in pretty slow. Then post cool, as slow as possible. I usually sit it on something non-heat conductive (concrete or something) and put a pot over it to keep the cool air off of it. That manifold stayed hot for ~1 hour before I could pick it up. Probably overkill, but I've never had a cast part crack. If I have an oven available, I'll usually preheat in the oven to 500, then heat with a torch but I this part was used and dirty so I didn't want to make a stink in the house.
