I have two gold rings I would like to solder together. The only problem is I don't want to directly apply solder to the gold. I was thinking I could bind them together with some wire and just solder it. Does anyone have any ideas?
Typically you would use a gold solder with the same carat as the gold you are soldering and some acid or borax flux. Maybe just stack them and use ceramic bricks to keep the alignment. You have to be careful because the melting point of the solder is not much lower than the rings themselves. Then there is just cleaning and polishing.
If you use a solder that isn't gold, it either won't work or stands a chance of spreading over the ring surface and then needing removing.
A jeweller that does repairs will probably charge less than it would cost to get the solder and equipment.
After scouting various jewellers, the lowest price I could find was about $100. All I would need is gold solder. I have the rest of the equipment. I was just wondering if I could solder a clamp to hold them together.
Silver solder will work, but it will flow across the ring surface and then need very careful filing and polishing to remove it. It would be easy to make a mess of the rings doing that, especially as the silver solder is harder than the gold underneath. With the right gold solder it's not a problem because the solder is essentially the same as the rings themselves so it just needs a bit of smoothing.
