COPPER FITTINGS A copper solder joint is created using the process of capillary attraction of a copper pipe or copper fitting and solder. After the copper tube and the copper brazing fitting are assembled and heated to the correct temperature, the solder applied to the neck of the copper brazing fitting melts. Thanks to capillary attraction, the solder is drawn into the gap between the copper pipe and the copper fitting, forming a strong and reliable connection. Copper soldering is one of the most reliable connections. All copper brazing fittings with a size of 67 mm and larger can be brazed with solid solder for brazing copper. Preparatory work for copper soldering with hard solder is the same as for soldering copper pipes with soft solder. For soldering joints with solid solder, you should use an oxygen-propane, oxygen-acetylene, or other copper soldering torch. For copper soldering, it is better to melt the solder using thermal conductivity, and not by direct heating with a torch. The gap between the insert of the copper fitting and the copper pipe must be filled with solid solder for copper soldering, so that a small rim is formed around the neck. If it is necessary to use flux for soldering copper, do the following: with the help of a brush, apply a sufficient amount of flux to the outer surface of the copper pipe and the inner surface of the copper fitting for soldering. Do not apply flux for copper soldering with your finger! Insert the copper pipe into the copper fitting so that the end of the pipe rests against the pipe stop, and then wipe off the excess flux. Heat the assembled copper solder joint evenly from all sides. Apply the brazing wire to the neck of the copper fitting, allow the brazing solder to melt and pour into the annular gap. Let the solder joint of the copper pipes cool down. Clean the joint as usual and rinse with water.
