How to Solder Copper to Copper

Soldering is a great way to join two pieces of metal together without needing any special tools or welding equipment. It’s easy, relatively inexpensive, and it produces a strong, reliable bond that won’t come apart easily. In this blog post, we will discuss the process for soldering copper to copper properly so you can create a secure connection every time.

Gather Your Supplies

Before you begin soldering your copper parts together, you’ll need to make sure that you have all the necessary supplies on hand. This includes a flux-core solder wire, flux paste (optional), sandpaper or steel wool, rosin-core solder wire (if using flux paste), an appropriate heat source like a soldering gun or torch, and safety gear like safety glasses and gloves.

Once your supplies are gathered, it’s time to prepare your parts for soldering. Start by cleaning off any dirt or debris from both pieces of copper with some sandpaper or steel wool. Then apply the flux paste (if using) in a thin layer over each piece of copper, where they will be joined together. This helps to ensure that the joint area is clean and allows for better adhesion when joining the two pieces together. Once the flux paste has been applied, attach one piece of copper to another with clamps or heavy paper clips, so they stay in place while soldering.

Now it’s time to start soldering! Begin by heating up your tool until it glows red hot. Make sure to keep an eye on it at all times, as too much heat can damage both pieces of copper being joined together. Once it’s heated up enough, touch the tip of the tool onto both sides where they are connected and apply pressure until the solder melts into place. Continue doing this until both sides are securely joined together, and then let it cool down before handling again.


Soldering is an excellent way to join two pieces of metal together securely without needing any fancy tools or equipment. By following these simple steps for how to solder copper to copper correctly, you can ensure that your connection stays strong for years to come! Just remember to always wear protective gear when soldering and keep an eye on your heat source at all times, so you don’t accidentally damage either piece of metal being joined together!
