How to Braze Brass to Brass

Brazing brass is a great way to join two pieces of metal together. It’s an effective and affordable way to do the job without expensive welding equipment. If you’re looking for a simple, straightforward guide on brazing brass to brass, then read on–this blog post has you covered!


What You’ll Need

Before you start brazing brass, you must have all the necessary tools and materials. This includes flux (or brush-on flux), an oxy-acetylene torch, brazing rods, safety glasses and gloves, a wire brush or grinding wheel, and a vise or clamp. You should also have your two pieces of brass ready and a fire brick or other heat-resistant surface.

Step 1: Clean the Metal

The first step in brazing is cleaning the metal parts with a wire brush or grinding wheel. This helps remove any dirt or debris that could interfere with the process. Make sure to wear safety glasses and gloves while doing this! Once your pieces are clean, use the vise or clamp to hold the parts in place while they are being welded together.

Step 2: Apply Flux

Next, take your flux (or brush-on flux) and apply it liberally to both pieces of metal, where they will be joined together. This helps prevent oxidation, weakening the joint’s strength over time. Be sure not to miss any spots–you want full coverage!

Step 3: Heat Up Your Torch

Now it’s time for the torch! Turn up the flame until it reaches a neutral color—not yellowish nor bluish—and adjust it to be about 4-5 inches long. Make sure your fire brick or heat-resistant surface is nearby so you can easily move things around during this step.

Step 4: Start Brazing

Now comes the fun part–it’s time to start brazing! Move your flame back and forth over both pieces evenly, but don’t let one side get hotter than the other; that can cause warping. As you do this, add small amounts of brazing rod into each joint until you have achieved a good seal between both metals. You must keep moving around because leaving one hot spot for too long can cause damage to your pieces!



With these steps in mind, you can confidently braze brass without needing expensive welding equipment or professional help! Just remember–safety first–so make sure that you always wear protective gear like safety glasses and gloves when working with heat sources like an oxy-acetylene torch! Good luck!
