How to Weld Copper To Copper

Welding copper to copper is a process that requires precision and skill. It’s not something you can learn overnight, and it takes time to master the technique. But with the right instruction and practice, anyone can learn how to weld copper successfully. In this blog post, we’ll be taking a look at the steps involved in welding copper pipes together.

Step 1: Prepping the Work Area

Before you begin welding, it’s important to make sure your work area is clean and free of debris. This includes removing any dirt, dust, or rust that may have accumulated on the surface of the pipes. Once you’ve done that, you can begin prepping the pipes for welding by sanding them down with fine grit sandpaper or steel wool. This will help ensure that there are no sharp edges or burrs that could interfere with your weld.

Step 2: Applying Heat

Once your work area is ready, it’s time to apply heat to the pipes in order to start welding them together. You should use an oxyacetylene torch for this step, as it produces enough heat for a successful weld without damaging the pipe material. When applying heat, be sure not to overheat the pipes, as they can become brittle and break when they are too hot.

Step 3: Applying Flux

The next step is applying flux onto both ends of the pipes before welding them together. Flux helps remove oxidation from metals during heating so that they can form a strong bond when cooled down again. Before applying flux, make sure both ends of each pipe are dry and free of moisture or oils, as these substances could interfere with proper bonding between the two pieces of metal during cooling. After ensuring both ends are dry, apply a layer of flux along each edge before joining them together and beginning your actual weld process.


Welding copper to copper isn’t an easy task, but with practice and patience, anyone can learn how to do it correctly and efficiently! If done properly, this type of welding job will produce strong bonds between two pieces of copper pipe that will last for years! Just remember to always prepare your work area ahead of time by cleaning off any dirt or debris before starting your project; then apply heat evenly across both pieces; finally, add flux before connecting them together in order to get a secure bond that won’t break apart easily! With these tips in mind, anyone can learn how to make quality welds on copper pipes!
