How to Join Copper to Copper

Joining copper to copper is no small task. It requires the right tools, materials, and techniques for a successful, long-lasting bond. Fortunately, it’s not impossible. With some preparation and patience, you can join copper to copper with just a few simple steps. Read on to learn more about how to do it!

What You’ll Need

Before getting started, you’ll need the following materials:

  • Copper pipes or tubing
  • Pipe wrench or pipe cutter
  • Soldering flux
  • Soldering torch and/or propane torch
  • Lead-free solder (60/40)
  • Clean rag or cloth

Once you have all the required materials and tools, you’re ready to begin. Here’s a step-by-step guide for joining copper to copper:

  • Use a pipe wrench or pipe cutter to cut the two pieces of copper that need to be joined. Make sure that you cut them cleanly and squarely so that when they are connected, there is no gap between them.
  • Clean both pieces of the pipe with a wire brush or sandpaper until all dirt and debris are removed from the surface of each piece. This will ensure that your joints are strong and secure.
  • Apply soldering flux along the inside edges of both pipes, where they will be joined together. This will help create a strong connection between the two pieces of metal by making it easier for them to bond together when heated up with solder later on in the process.
  • Heat up both pieces of the pipe using either a soldering torch or a propane torch until they are hot enough to melt solder onto them without burning it away too quickly (around 500°F).
  • Place lead-free solder onto both pieces of piping before joining them together so that when they cool down after being welded together, they remain sealed properly at all points along their length where they come into contact with each other.
  • Once everything is heated up enough and cooled down, wipe off any excess solder with a clean rag or cloth and inspect your work for any weak spots in order for your pipes will last as long as possible without cracking or breaking apart under pressure over time.


Joining copper to copper may seem like an intimidating task at first, but by following these steps carefully, you can make sure that your project comes out looking great! With some patience and preparation, anyone can successfully join two pieces of copper piping together without spending too much time or money doing it; just remember not to cut corners when cleaning the surfaces before soldering – this is key! Once everything has been correctly prepared, heating up both pieces of metal with either a soldering torch or propane torch should take care of things in no time – good luck!
