Tig welding!!

[SlamDunkel]

Neat. I've had great success with sanitary welds using a second flow regulator with Argon for a purge weld technique. Nitrogen can do the same. As long as Oxygen similar gasses are not on the other side of the welding work you won't make barnacles that host bacteria. It is important to close the other side of the weld work. I don't like threaded connections either for this reason.

That looks like inch and a half tube? I'm guessing. I'd fuze it at about 75 amps. No filler. Purge at 10-15.

Here's my work

Yea think it was 1.5 tube it was just scrap work laying around I could play with. Had my purge set alittle low and just need to bump my amps and sit on the crater alillte longer sweet might have time to
Play alitte more tonight

And dam that sick^^^

 

[1fast636]

Well had 5 mins for a quick try and it worked uped amps to 70 and had purge going at 15, I didn't take my time because it was last 5 mins before leaving lol

Might have to zoom in to see it but I'm pretty excited lol and it was only about 2.5-3 inches long and I dipped my dam tungsten lol

Hungenjapan got a question welding fittings into a keg would it be easier to just back gas it or would there be a way to purge the hole keg and do it that way? Any insight would be awesome I'm still learning and practicing so got plenty of time to learn

 

[hugenjapan]

Is there more than one fitting in the keg? That changes everything

 

[1fast636]

For my herms hlt there will be 5 fittings and the top cut, in my mash tun bottom drain inverted keg and one fitting on the top side for recirculation bottom (top) cut off , boil top cut off 3 fittings whirlpool port temp gauge and drain

The best way to fittings like that is to use a piece of aluminum foil and tape it onto the backside of the fitting so it has at least an inch gap between it and the fitting (so you don't burn through the foil) and poke some holes in the foil for the argon to flow out then purge through the other side of the fitting. Weld the outside first with some filler so that when you weld the inside after (it you choose to do so) there is more material there so you're less likely to burn through. Sorry if this is confusing. If you have any questions don't hesitate to ask.

[hugenjapan]

Ya that would probably work.. More than my work would buy for us or allow us to spend the time to make.. Lol

 

[1fast636]

Lol yea I do all this on breaks or after work on my time I might have another idea let me brain storm today and I'll get a drawling made up on what I'm thinking see what you think

 

[1fast636]

Looks better than most of the welds I see at work!

 

[sandyeggoxj]

Here ya go:

 

[1fast636]

Looks like I found the next thing I'm making, my round one will work nice for nipples into the keggle but on long pcs it wasn't the greatest, although I could of had the flow up a little more to fill the voilds at the top and bottom probably too.

 

[hugenjapan]

You don't even need to use gas to purge the back of an open corner weld.. Just put a piece of non ferrous material clamped tight on the other side and giver.. I do it all the time

 

[1fast636]

Interesting will try tomorrow

Looks pretty good. I wish I knew tig, but I've only learned mig and stick. Someday.....

Keep practicing and if you get the chance try tig out it use to scare me before I started now it's the only welding I want to do lol
