whiskeytango Posted November 19, 2013 Share Posted November 19, 2013 Lame question but what exactly does sanitary welding mean? How is it different from regular welding? Link to comment Share on other sites More sharing options...
leftturndistilling Posted November 20, 2013 Share Posted November 20, 2013 No Scratches, voids, cracks .. must look polished ... Nowhere to hold debris ... Link to comment Share on other sites More sharing options...
tipk99 Posted November 20, 2013 Author Share Posted November 20, 2013 Sanitary welding provides a smooth inner surface that has no nooks and crannies for things to hide in. In dairy and brewing its important because you don't want bacteria. I wad curious because in a still you are getting up to temps thatwould kill bacteria... So I was thinking a smooth weld would be good enough. Even if not to sanitary standards. Link to comment Share on other sites More sharing options...

tipk99 Posted November 20, 2013 Author Share Posted November 20, 2013 What are the consequences of not using a strict sanitary weld? I'm not talking about a sloppy, loose weld, but a good clean, smooth weld (and passivated)... Anyone else out there care to chime in? Not that I don't value LeftTurn's opinion, but he the only one so far... Thanks Tom Link to comment Share on other sites More sharing options...
Lenny Posted November 20, 2013 Share Posted November 20, 2013 I certainly can't speak with the level of expertise that Brain from Leftturn and a few others probably could, but... if your talking about welding a piece of equipment that you care about or spent a good chunk of change on - do it right. If it's temporary or experimental - I say go for the dirty weld if it gets you where you need to be. Depending on how dirty... my understanding is that you risk contaminating the stainless with impurities that can weaken the weld, cause pitting and potentially rust. I've had a few bits stuck onto stainless vessels without a completely sanitary welding process (back flushing with argon - and/or whatever else a welder who knows more than me would do), and those welds are holding up just fine, but these are on some crappy tanks that I could care less about.

Michaelangelo Posted November 21, 2013 Share Posted November 21, 2013 Any reputable tank supplier should be providing you product with sanitary welds as well as fully passivated. Link to comment Share on other sites More sharing options...
