How to Solder Copper Solder Fittings
Copper solder fittings are soldered to copper pipe or tubing during the installation process. The first step involves cutting through the existing tubing or pipe. You can either use a hacksaw or a copper tube cutter designed specifically for the task at hand. Although both make an acceptable cut, the tube cutter ensures a square cut and tends to leave fewer burrs. When using a tube cutter, hold the tubing in place by a vise or clamp.
After you cut the tubing, remove the burrs from inside the pipe. You can do this with a simple wire brush designed for that specific purpose. However, if you are cutting your tubing or pipe with a hacksaw, it may be more effective to use a half-round file to help remove the burrs, as there may be many more from this method of cutting.
Keep in mind while cutting your tubing or pipe that an allowance must be made for how much the fittings increase and the overall length of the run. It will vary depending on the fitting being used, but a general rule of thumb is to add about a half-inch for each fitting to the length of pipe you cut.
Before attaching the fitting to your pipe, clean the end of your tubing or pipe with a cleaning brush. The area that is inserted in the fitting must be cleaned until it is bright all around. If the cleaning brush doesn’t accomplish the task, use sandpaper or steel wool. Double-check your copper fitting to ensure that there is no debris or foreign matter inside, as this will cause an ineffective seal.
The next step is to apply a light coat of flux or soldering paste to the cleaned end of your copper pipe or tube, as well as the inside of your fitting. This ensures a firm bond between the copper and solder and will help the copper for oxidizing when heated. Place the copper fitting on your pipe after it is thoroughly cleaned and coated. When it is firmly in place, rotate the pipe and fitting a few times to spread the flux or paste evenly.
The most common way of sweating a copper pipe is by using a propane torch. Use the propane flame in the middle of the fitting to heat both ends evenly. Don’t apply heat directly to the fluxed area, and be careful not to overheat the copper pipe. If you look at the flame on the side of the pipe away from the torch and there is a green flame, this means the fitting is ready to solder.
Once the fitting and pipe are ready, apply the solder to the pipe where it joins the fitting. The solder should flow easily into the fitting. You only need a bit of heat around the whole circumference of the tube. After the solder melts, wipe away the excess with a towel and let the fitting cool before touching it.
