Lanny have you seen capacitive discharge stud welding?
Yes I have a stud welder but I did not realize it would weld dissimilar
metals especially aluminum to anything else.
Stud welding is very finicky and will leave a blemish on the opposite side
of thin metal.
When a stud weld fails you have to grind the surface to clean it up before
rewelding.. How are you going to do that if it is between the other studs?
Attaching studs, fins or anything to a pot is going to be problematic, but
attaching something to the pot holder may be practical. The heat transfer
may not be as good as having something attached to the pot but it could
possibly improve the heat transfer.

Lanny have you seen capacitive discharge stud welding? This would
allow welding of dissimilar metals to the pot in any pattern. I have
no idea of costs.
Have you done heat transfer tests with your 4mm aluminium pot compared
with the thinner stainless one? Stainless is a notoriously poor
conductor of heat and theoretically would need to be just under a
tenth of the thickness of aluminium for the same conductivity, but I
do use stainless pots at home.
Finally can you explain the difference between a vat and a pot?
Paul I do consider this to be important because biomass stoves have an
inherent problem with heat transfer compared with natural gas or LPG
so improvements in heat exchange will have high benefits.
