Catch Can / Attempt at TIG welding!!

[Jason]

So this is my second TIG project that I decided to do on budget with materials laying around. Never touched a TIG before my exhaust and this. It is a simple catch can for my car so I don't run the crank case vent into the intake and track oil through my intake manifolds and intake runners and then burn it. This will allow the oil to fall to the bottom of the can and the vapors to exit out of the filter. Like I said this was my second time with a TIG and any advice would be accepted.

Filler was 1/16 308L
1/16 1.5% Lanthanated Tungsten
~45 Amps
16ga 304 stainless
5 - 7 LPH Argon
The nipple were made from Galvanized steel pipe and ground on a little but I don't think enough.. Still was hard to weld to.

I started with 2 pieces of the pipe.


Cut one in half and then flattened and then cut/ground into circles for the top and bottom lids


Welded top and bottom on. I started using filler but it was leaving a thick bead as there was a slight edge on the top and bottom pieces that melted. These ended up being done with no filler rod used. About 1 to 2 inches at a time between rotation..





Here you can see the nipples added on. The one on the side was pushed into the can a little and then the top sat against the surface. I think these still had some of the galvanized coating as they popped some and turned everything all white. I wire brushed them after the weld was complete.




And installed it into the car..
