Welded up some kegs for a buddy of mine this weekend.
Beautiful as usual lehr. Nice work.
Hey lets see a pic of that bad 67 z !
Maybe you should just travel from town to town welding brewstands and keggles for us. You could probably drink yourself to heaven and back with free homebrew if you took it up.
Great looking welds, what gauge are those tank walls?Welded up some kegs for a buddy of mine this weekend.

What's the tape on the fittings for, not the teflon, are you back purging? Also is the brass to absorb heat and to help distortion? That's what I do, I don't back purge as I don't have a splitter for my regulator.
I wish I were a buddy of yours.
Can you get me a pic of your back purge(back gas) setup? When I did some pipe welding a long time ago, I back purged, but forget how the argon came off of the bottle. Wondering what I have to buy to have back purging capabilities.
Thanks,
Morgan
what size tungsten do you use?
Your are my buddy you just live a long ways away !

What does the inside weld look like?, is it ground and polished smooth.
I'm closer Pat......=o&o>......
I use 3/32 and it works the best, I have a hard time using 1/8" for anything less the 1/4" thick stock.
So the inside does not get back welded and ground like this then http://picasaweb.google.com/kevin.ladue/KegglesForClubMembers#5194106467776001890.
My thinking to face off the coupling end removing the external radius then machining a reduced step to the thickness of the keg with a snug fit.
My Synchrowave's limits are 3 to 385 amps output.
I dont think I have ever welded anything that thick with my tig but aluminum.
I do think you could weld a keg with 1/8th inch once you got your amps right.

What pulse rate?Have you tried pulse at 100% / 70% current, it makes it easier on the inside when back welding the couplings.
Yeah, definitely could, but I don't have my hand in it enough to go with anything but the 3/32", that's what I am used to. What pressure do you use when back gassing?
