I've a set of stainless pans on which spot welds have failed. I'm not sure exactly what type of stainless it is austenitic / martensitic or what have you but it would be a shame to throw out a couple of hundred pounds worth for a repair.

What type of flux and solder would I need?

I've got a torch, various gases, abrasives Kaptan masking tape and suchlike, just don't know what flux and solder to use..

Out of interest, before now, when the handles were still attached - did the handles get hot when on the hob? If they did not, you'll find there's a slither of insulation between the pan and handle too - and you may like to think about how this would be restored. Getting them spot-welded again, or may be brazed is likely the best way to go though, you don't want the solder softening (and handle falling off) with the heat of the combustion products from a gas hob. Spot welding would be neater and negate having to restore the surface.

I doubt your going to be able to solder these, they would be better welded.

I can't recall the handles getting hot.

I've brazed stainless before, might take a bit of clean up afterwards though..
 
Hmm, I'll give that a go. Hella waste of materials through.

What specific materials do I need? It's still like to know how to join S/S regardless if I use the warranty
 
For a perfect invisible repair the parts need to be spot welded together.
However, you can gas weld stainless using a carburising flame and most importantly, the correct flux, typically SIFBronze stainless. For this, a stainless spelter (filler rod) is also needed.
You can braze stainless with the same flux and a brass spelter but it will not be particularly neat - expect the spelter to run and distortion to occur.
Occasionally the flux will disappear if the material is overheated and the resulting oxidisation will require the job to be started again.
Limited experience I've had, generally dealing with stainless car exhausts.

Could be a good move - if you can get the correct rivet snap and setting tools, together with a stainless rivet, of course (y)

If John Lewis won't honour their lifetime warranty (they should) then take them to a local welder to get the handles properly welded on
