Did someone break your favorite silver tablespoon your grandmother gave you, or did your silver ring burst? You can, of course, give the item to a jeweler (the cost of work, as a rule, is one third of the cost of a silver item), but it is more rational to get down to business yourself.
It is necessary
torch, flux, solder, brass
Instructions
Step 1
To solder small parts, use a soldering iron with a small tip or use a small gas torch, especially since it requires a regular gas canister to refuel it, and the price ratio of the cost of effort and equipment in relation to the quality of work turns out to be in a positive sector.
Step 2
Buy solder (here it is advisable to find refractory solder (t from 240 degrees) of the brands PSR2, PSR2, 5), or buy a special paste (which is much more expensive), buy a flux.
Step 3
Thoroughly clean the soldered surfaces from grease, dirt and oxidants, be sure to coat the junction with flux, place a piece of solder there.
Step 4
Before soldering, think over the clamping system, fix the parts to be soldered and thoroughly warm up their edges, then put the parts on a sheet of asbestos and start heating with a powerful flame of a gas burner, here it must be remembered that the soldered place must be cooled and only then processed with sandpaper.
Step 5
In addition, solders with a lower silver content can be used for brazing silver, but in any case, it must contain Ag. Remember that in none of the workshops, without your knowledge, no one has the right to use tin or other low-temperature solders to solder silver, this is possible only with your permission. In the future, if the master again uses high-temperature solder in this place, then your silver chain may simply burn out.
Step 6
What if you don't sell flux in your stores? Do it at home. Take borax and put it in a glass dish. Fill the borax with water and use a water bath to heat the bottle. Cool the resulting mixture, and grind the crystals formed in a mortar. That's it, the flux is ready for use.
