I gas welded a lot of stainless steel in my early years, before I owned
my first TIG, and it does work, but you get horrendous heat distortion,
and if you keep it molten too long it will crack like crazy due to
chromium carbide formation.
All high temp silver solder will work. ( I am talking about silver
brazing alloys, not low temperature solder that contains silver. )
But some will work better than others. The alloys that are especially
good for stainless contain a few percentages of Nickel. They wet the
stainless more easily.
If the repair was on the inside of the pot, I would say to stay away
from the silver brazing alloys that contain Cadmium. You won't find
these in new stock, but could find some on ebay.
A little looking on the internet will come up with lots of
I just wish they left more offerings of roast meat before heading back
down the mountain.
I do find it puzzling when I go to answer a question, and find somebody
already answered it with a quote from me.

When you are Da Welding Wizard...all bow before you.
How do you like your complementary copy of the Welding Bible, Starring
Ernie Leimkuhler, as the Great One?
You did...did get your genuine gold finshed, hand rubbed pigskin copy,
printed on fireproof parchment with flame resistant tassles.....right?
"First Law of Leftist Debate
The more you present a leftist with factual evidence
Ernie, can you recommend a cadmium-free silver solder and flux
so I can re-join my 10" SS Chef's knife?
Are these what I want?
That is high temp solder which would work on the cooking pot, but for a
knife you want something that flows at a lower temperature or you will
trash the heat treat on your blade.
For knives we usually use what are called "silver bearing" solders, or
tin solders with some added silver for strength.
They usually flow below 350 degF
They can normally be found at hardware stores, in a package with some
Real silver solder is much stronger but flows at a much higher temp,
like 1000 - 1200 degF
