What is the process for soldering findings onto 950Pd rings?
The setting and shank should be pre-finished with fine grade abrasives and pre-polished. The two pieces should have a tight fit with no gaps and irregularities at the connecting joints. No fire coating or flux is used, only easy flowing palladium solder. If the pieces require holding devices, they should be palladium, platinum or tungsten carbide tip tools. Avoid contamination from other metals or debris with palladium. No pickling is required after joining. Like with gold, mechanical restoration of the polished luster will be required after assembly and soldering.
