Title: Welding thin stainless
Post by: rukkus on March 08, 2015, 07:35:02 PM
I have a couple of those german stockpots with 1/2 holes drilled for a tap and a thermometer. Its a total pain getting them to seal up. The pots are very thin. Has anyone managed to weld fittings to these?

yep welding a 1/2" socket on would do the job for both the thermometer and the tap. I'm using a 1/4 bsp right angle for the sight glass

I basically wasted today trying to seal them up when ideally they have welded sockets anyway

Ruckus,
You could get some of this

It's great for sealing weldless joints etc.

Should have said, you have to cut a bit out to fit around seal.

Is that similar to the silicon backing sheets? i cut up lots of those today

Cool, my main concern is that the stainless is very thin so it could be a pain. If you could PM me an idea of cost when you know a bit more that'd be awesome. We could have met in Simons alright. I'm @davidconde on twitter.

I think I already have all 4 sockets. If it was possible to also weld in the 1/4" for the sight glass it'd be really cool but its not a biggie as i have that sealing i think. I see you are putting together an all grain kit yourself. You are more than welcome to pop over when I'm brewing some time.

I see the tell tale signs of too much heat being used for the thickness of the metal but at least a good color on the welds.
