Best Glue or Epoxy
What is the best Glue or Epoxy for bonding 2 pieces of metal together, has to be permanent but doesn't have to be particularly strong.

Got the square peg in the round hole, now can't get it out !!

What are the load/force/torque/vibration/environment exposure requirements?

Best Glue or Epoxy
If it doesn’t have to be strong I’d say pretty much any epoxy adhesive. Metal needs to be roughed up well, particularly if it’s aluminium.

"best" is a very subjective criteria -- especially when teamed with "doesn't have to be particularly strong"
3M make a range of metal bonding epoxies some of which are claimed to create a bond as strong as that achievable with welding.

Knowing that it is only a thin sheet of stainless with markings, I'm also thinking double-sided tape or contact adhesive

Double sided tape mentioned a few times - am vaguely aware of some incredibly strong double sided tapes currently available. A quick google of "strongest double sided tape" yields this
VHB tape, or Very High Bond tape, is an extremely effective double sided tape that's used in place of rivets, bolts, welds and screws. It's easy to apply, but so strong that it's a significant component of the Burj Al Arab one of the tallest (and arguably the most luxurious) hotels in the world. It flexes like chewing gum and made it a great choice for affixing the cladding of the Burj Al Arab.

Dont know what you lot might think but intuitively, for me, I'd like to have a few mechanical fixings in that cladding as well.
In the next 5 years will super strong adhesives mean that I don't have to learn how to weld ?
or braze ? ie stick a carbide insert down with supersupersupertape ?

I have witnessed a test for the sign industry in which two sections of colorbond were fixed by overlapping using VST (very strong tape) the sections on being forced apart resulted in the colorbond tearing before the joint failed

The issue with tape is some of the adhesives used will be affected by mineral oils and solvents. I've seen many (mainly Chinese) similar plates fall off equipment through a combination of solvents, rubbish adhesive to begin with, and different expansion rates with temperate changes.
If the fit is reasonable I use Loctite 680 for this type of thing. Otherwise plain old super glue would probably do the trick
