What is solder paste? How to use solder paste for jewelry?

 Solder paste is a combination of dust and flux, which are both necessary to join two pieces of metal together properly.

SilverSolder paste for jewelry, like any other kind of solder comes in a variety of alloys, especially silver and gold.

Solder pastes that melt at various temperatures are also available.

It is basically the same as any other solder you can buy, with the added benefit of being pre-mixed with flux.

Use Solder Paste for jewelry:

·        The fact that a solder paste syringe comes in a syringe is one of the nicest aspects of utilizing it. This allows for an extremely exact solder paste application, which is ideal for joining jump rings together. Simply unscrew the cap from your syringe and insert the needle that came with it.

·        Make sure the metal you're soldering is nice and tidy of dirt or oily fingerprints before you begin. This can obstruct the soldering process, making it harder for the solder to flow smoothly through the connection.

·        Check to see if the soldered joint is entirely flush. File until there is no more light leaking through the join. This will ensure that your solder bond is as robust as possible while also allowing the solder paste to flow smoothly through it.

·        Apply a little amount of solder paste to the solder joint or the metal surface that will be soldered. Administer a little force to the syringe plunger - you'll become used to the pressure needed to apply the little quantity of solder needed to solder findings quickly.

 

·      Replace the cap after wiping away any leftover solder paste from the needle. Make it a practice to do this promptly after each usage to keep your solder paste in good shape for longer.

 

Solder with solder paste

You may now apply heat in a circular pattern to the solder joint. Use the same circular movements to heat the whole piece of metal as you would with a solder strip or wire. You may focus the heat more precisely at the solder junction when the piece of metal approaches annealing temperature (a dull cherry red glow).

Please remember that the flux in your solder paste mixture will ultimately bubble and burn away.

You may notice the solder balling up as you proceed to heat the solder junction.

If the solder does not fall entirely in the correct area, don't be concerned. Ensure to direct the flame's heat toward the junction, as the solder will be pulled to the heat.

Are you dissatisfied with the solder joint?

Simply reheat your piece by re-cleaning it, adding additional solder paste to the connection, and following the instructions above.

Quench and pickle your solder junction after you're satisfied with it to remove any oxidation. If any burrs or extra solder are discovered at the junction, just file them away for a tidy, professional finish.

Final Words:

The fundamental benefit of solder paste is that the syringe in which it is stored allows you to reach small locations for precise soldering.

It's perfect for welding jump rings or earring posts, or for adding fussy intricate metal pieces to your new design
