How To Solder Jewelry

How to Solder Jewelry - JewelryLab

Whether you are a beading enthusiast or a budding metalsmith, soldering can be an invaluable lesson to learn. From permanently closing those unreliable jump rings to the prospect of adding new depths to your existing skill level, soldering can add so much more to a jeweler’s life. I completely understand though, the hesitancy that you’re feeling. A torch is not a toy, it is a serious tool that should never be taken lightly. However, I assure you that soldering can be safely accomplished at home and will help you further your journey to make cool mens rings and women's chains. 

Now, you don’t need a studio, a garage, or a jewelry bench, you can create a safe soldering space on a kitchen table with just a few items. Set up your space, take time to practice and your fear of soldering will quickly become a thing of the past. In no time at all, you’ll be closing those jump rings, joining those links, and permanently soldering close those finger rings.

Note: Stay focused! When you first begin to solder, remove all the distractions, such as pets and phones, from the room and make sure you have plenty of ventilation.

Let’s get started…

When soldering any metal, a few variables are depending on what is being soldered, but for the most part, you follow the same series of steps each time you solder metal.

First, you need to set up a safe area to solder. This will normally require a large ceramic tile, fire brick or heat resistance pad, and an overhead lamp. The fire brick is put on top of the tile. Also, make sure you work in a very well-ventilated area. Some other items you want to have nearby are a pair of copper tongs, a jar of water, a small paint brush, your solder and flux, and a pickle pot.

Prepare Metal 

Next, it’s important that whatever is being soldered is clean and free from grease and oils that have been transmitted to the metal from your hands. So, each piece that is to be soldered should be put into a pickle for a few minutes. After taking them out of the pickle, use a pair of pliers or tweezers to handle the metal and arrange it on the fire brick in preparation for soldering.

Add Flux

Once the pieces to solder are cleaned and arranged on the brick, it’s time to cut your solder. Just as the metal should be clean, so should the solder. Though you don’t need to pickle it, you want to make sure you don’t handle it a lot. Either use wire cutters or very sharp scissors to cut tiny pieces of solder. Set them aside on your tile for later.

Now it’s time to flux. There are two different ways and use two different kinds of flux. It's a matter of personal choice. You can do either of the following:

Use a type of flux called Battens. It’s light yellow. The flux is applied to the area to be soldered using a thin paintbrush. Then the solder is placed on the metal. This way the flux and solder are heated at the same time.

The second way is to use a borax-based flux that is more like a paste. The flux is again applied with a thin brush. However, instead of immediately applying the solder, the metal is heated first until the fluxed area looks like glass. Then the solder is placed on the metal.

If you need some extra time to arrange your solder, then it seems like choice B works better because it also makes the soldered area a little on the sticky side. However, it seems like an unneeded extra step because choice B requires you to heat the metal twice, while choice A allows you to flux and heat the solder at the same time.

Place the Solder

Tweezers work well for placing tiny pieces of solder onto the metal. When placing the solder on the metal, it should be positioned between the areas that will best join the metal. A little solder will go a long way if placed correctly. Unfortunately, this requires some practice.

Torch It

Once the solder is in Place, it’s time to start up your torch. First, all the metal should be heated so that the temperature for soldering is reached at the same time. The solder will follow your heat, so try not to point the flame right at the solder. Instead, you want the flame to draw the solder through the joint being connected. Continue to keep the flame on until you will see the solder run, then remove the flame immediately.

Quench the Metal

Using tweezers or pliers, pick up the hot metal and drop it into a jar of water. If you need to solder the piece again, you’ll need to repeat these steps. Remember to change to a different kind of solder, either medium or soft. as described previously.
