Hi, I've had this set of stainless steel Prestige saucepans for about
18 years.Recently a couple of the pans overheated on the hob and the outer 1 or
2mm layer of copper on their bases warped away from a thicker base layer of aluminium. The thin discs of copper are now half on and half off.I'm guessing that the best approach for repair purposes would be to re-overheat the pans and attempt to remove the copper completely and clean both faces. Then perhaps reheat, re solder and clamp the copper sheet firmly to the bottom of each pan before it cools.
Will the solder used be an unusual type where the joining of copper and aluminium is concerned?
Any tips on other aspects of this repair job?
