How to Weld Keys

You will need safety gear to weld keys.

Welding keys that are damaged is not a difficult task, but you must know how to use brazing equipment. Keys are made out of brass because it is a soft metal that is easy for key-smiths to cut. To weld keys, you must braze them using an oxygen-acetylene welder with a flux-coated brazing rod.

Things You'll Need

• Welding gloves
• Welding goggles
• Welding jacket
• Grinder
• Oxygen-acetylene welder
• Brazing rods
• Flux

Instructions

1. Clean the metal free from any debris on your keys using your grinder. You want to expose the metal to ensure a strong weld.

2. Place the two pieces of metal 1/16-inch apart and in the position that they need to be welded in.

3. Coat a welding rod in flux and set it aside.

4. Hold your torch in your dominant hand and heat the keys with your torch until they are red hot. Do not melt them.

5. Hold your flux-coated welding rod in your non-dominant hand. Heat it up with the torch and drip the rod into the gap between the keys. Let the key cool before use.
