No. The pipe leg is welded to a piece of 1/8" stainless steel that was formed to match the shape of the tank and then welded all the way around it's edge.. This panel is about 8 inches in diameter, and can be seen in he pictures. A crack in this panel will not penetrate the tank. It is a very clever idea, and makes working on the tank legs much less problematic.

I still don't understand why the tank legs are steel and not stainless steel, but maybe in the 1960's in England Stainless steel was really expensive, so they only used it where they had to.

Mike (and Miss Jaime) have both been posting over on the Digital Photography newsgroup. Coincidence???

I always thought it a bit odd that one or the other would post to a group, but only rarely would both post at the same time. Hmmmmm...........Coincidence?

Could you have used CO2? It's something that would be plentiful in a brewery. Engineman1

When the tank tumbles over, hope somebody is there to slurp up the beer! Ciao, David Todtman

CO2 is not inert. Nitrogen will work, but Argon is better.

I am assuming that there isn't a problem welding the steel leg to the stainless pad, using the TIG. Would there be any problems with this since they are dissimilar metals. How do you determine which filler rod to use when mating two diferent metals. Something I have never had a chance to do yet. Cheers,

Actually what I am welding is the broken edge of the 1/8" stainless pad, so it is more like welding a stainless weld bead to a stainless pad. Normally for dissimilar metals I would use Hastelloy W or Inconnel 625.

309SS is the most common alloy used for that purpose.

Ernie's favourite is a Hastelloy rod. Since I don't have any, I use 312 or 309 stailess or Inconel 625, 82 or HX for joining dissimilar ferous metals. e.g. An extreme case: H-13 to mild steel.
