Why are "sanitary" welds needed on a brew kettle if they are getting boiled.

there are points in your brew when you are not boiling correct? just like why would i back purge a water line in a process plant when i know their goin to clean it with boiling acid? because its the proper method......plus if i saw you had "surgar" on your welds on ur keg i woulnt drink that beer....

My first pot was a 10 gal Polarware, ouch. I took it to a guy that said, "Oh yea I can weld sanitary stainlesS." He burnt the hell out of the pot, no purge, and created sugar mountain on the inside along with his filler wire hanging in the inside. That said, I've made award winning beer in that kettle w/o any problems. I used it for everything, as it was my only kettle. It bothers me every time I see it, but I've had no issues. I have learned to do my own stainless welding. It may not be pretty, but it's mine. I think this issue is overstated about potential problems. I wouldn't want to use it on the cold side for sure. If it were still the only kettle I had, I would still be brewing with it today frowning everytime I looked at it.

There's not much to worry about with a boil kettle. Still, a smooth weld would be nice.

I find sanitary welding to be an extreme challenge. The next time I have a stainless project, I'm probably going to silver solder it rather than weld. I never seem to be able to eliminate ALL of the imperfections, no matter how careful I am with back purging. I think my issue is heat control rather than weld protection.

I'd rather weld it, but I just don't TIG weld often enough to stay in practice. I can usually get into the swing of things pretty quickly with mild steel, but I don't do enough stainless to keep my skills where they need to be. I have only myself to blame - I'm sitting 15 feet from the TIG rig in my garage.

if you make the hole just barly big enough to let the face of the coupling touch the face of the keg wall witch i have filed an polished to remove natural oxidation...then i do a fuse pass at about 40 amps...then i go over that with 1/16 304 fill rod...and i always careful which way i push my heat...any questions feel free to ask

Do you place the fitting entirely inside, entirely outside, or partway through the keg wall?
