How to Weld Brass to Brass

Welding brass to brass is tricky, but it can be done with the right materials and technique. If you want to know how to weld brass to brass successfully, this guide is for you! We will cover the best methods and materials for welding brass together and tips for achieving a clean, strong weld.

Step 1: Select Your Materials

Before you start welding, you’ll need the right materials. For welding brass to brass, we recommend using a TIG torch fitted with a collet body and cup specifically designed for welding these metals. You’ll also need tungsten electrodes in size 2% thoriated or pure tungsten; these electrodes should be sized according to your application’s requirements. Finally, make sure you have some quality filler rods on hand, such as silicon bronze or aluminum bronze.

Step 2: Prepare Your Work Area

Before starting your project, ensure your work area is properly set up. You’ll need to ensure that no combustible materials nearby could catch fire during welding and create an unsafe work environment. Additionally, use safety glasses and other protective gear when working with hot metal and sparks from the torch.

Step 3: Connect Your Torches

Now that your work area is set up and ready to go, it’s time to connect the torches and get ready for welding:

  • Attach the collet body and cup onto the TIG torch head. Then tighten them firmly so they won’t become loose during operation.
  • Insert the tungsten electrode into the collet body and tighten it carefully but firmly with a wrench; this will ensure a secure connection between the two parts.
  • Connect your filler rod by attaching it to one of the clamps on either side of your torch head; this will allow you to feed material into your weld joint easily while still keeping both hands free for manipulation of the torch head itself.

Step 4: Begin Welding

Now that everything is connected correctly, you can begin welding! Start by setting up your amperage level according to your application’s requirements; too much amperage can cause warping or cracking of the metal, so make sure it’s set correctly before beginning! Once you’re all set up, simply strike an arc between your tungsten electrode and filler rod, then slowly feed more material in until you’ve achieved a solid weld joint between both pieces of metal!


By following these steps closely, you should have no problems successfully welding together two pieces of brass! Keep in mind that this process can be dangerous if done improperly, so always take proper safety precautions when operating a TIG torch or any other type of welding equipment! Remember—practice makes perfect! With enough practice, even novice welders can learn how to weld together pieces of metal like brass with ease and safety! Good luck with all future projects!
