How to Weld Gold

Some welding techniques for gold jewelry require the use of a torch.

Fixing your favorite piece of gold jewelry, requires a process known as welding. The experts call this method "fusion welding." Permanent welding does not require soldering or torching. Fusion welding instruments are commercially made and have a small nib that comes from the base of the device. When contact is made between the welder and the precious metal, an electrical charge emits from the welder. The gold pieces melt together and instantly solidify.

Things You'll Need

• ABI Tack II welder
• Heavy tweezers
• Pliers
• Gold jewelry pieces

Instructions

1. Weld two pieces of gold such as a gold earring with a broken post. Place the back of the earring at the weld joint flat on a weld contact pad. Place the other gold piece perpendicular over the location where it's to be attached. Use heavy tweezers to hold the earring and pliers to secure the post.

2. Depress the foot pedal of the ABI welder. Set the welder at 40 volts, a low energy setting. Connect nib of the welder with the earring at the fusion point. Apply light to medium pressure to successfully weld the two gold pieces. The fusion weld is completed instantly.

3. Polish the jewelry, if desired. No significant repolishing is necessary. Do not remount or reset stones or remove or replace clips.
