Cleaning copper tubing properly is crucial for a successful solder joint. This involves removing any debris, burrs, or old solder to ensure a clean, strong bond. Here's how to do it:
1. Deburring the Tubing
- Use a deburring tool to carefully ream or deburr the inside of each pipe.
- Run the tool around the inside, removing any burrs. [Reference 1]
- Ensure that copper shavings don't fall into the pipe or fitting. Tap the pipe gently to remove any loose shavings. [Reference 1]
2. Cleaning the Exterior Surface
- Removing old solder: If there's old solder, carefully wipe it smooth with a thick rag, using straight strokes to avoid burns. Wear gloves. [Reference 2]
- Abrasive cleaning: Use 100-grit sandpaper or emery cloth to clean the copper until it's shiny. [Reference 7] Scuffing pads can also create a clean, satin finish. [Reference 3]
- Removing flux: After soldering, remove excess flux with a damp rag, ideally while the pipes are still warm. [Reference 4, Reference 8]
3. Preparing for Soldering
- Thoroughly clean the area where the solder will be applied. Any residue will prevent proper adhesion.
- Apply flux to both pipes and the coupling to facilitate soldering. [Reference 7]
Remember, proper cleaning is essential for a successful and lasting solder joint. Using the right tools and techniques ensures a clean, professional finish.
