Solder does not bond with copper because they have different atomic structures and properties. Copper is a metal with a high melting point and good electrical conductivity, while solder is a metal alloy with a lower melting point and is used to join metals together. When solder is heated and applied to copper, it forms a mechanical bond rather than a chemical bond, as the two materials do not chemically react with each other. This is why flux is often used when soldering copper, to help clean the surface and promote adhesion between the solder and copper. **

To solder copper pipes correctly, start by cleaning the ends of the pipes and the inside of the fittings with a wire brush or emery cloth to remove any dirt, debris, or oxidation. Next, apply flux to the cleaned surfaces to help the solder flow and create a strong bond. Then, heat the joint evenly with a propane torch and apply the solder to the joint, allowing it to melt and flow into the joint. Finally, wipe away any excess solder with a damp cloth and allow the joint to cool and solidify before testing for leaks. **

To hard solder a copper kettle, you will need a propane torch, hard soldering wire, flux, and a heat-resistant surface. First, clean the surfaces to be soldered with sandpaper or a wire brush. Apply flux to the cleaned surfaces and then heat the kettle with the propane torch until it reaches the melting point of the hard solder. Once the copper is hot enough, touch the solder wire to the joint and allow it to flow into the gap. Finally, let the kettle cool and then clean off any excess flux. **

A copper ring is a piece of jewelry made primarily of copper metal. It is a circular band that is worn on the finger as an accessory. Copper rings can come in various designs and styles, and some may also incorporate other materials or gemstones for added decoration. Copper rings are popular for their unique reddish-brown color and are believed by some to have healing properties. **

To solder a leaking copper heating pipe, you will first need to turn off the water supply to the pipe and drain any remaining water. Then, use a pipe cutter to remove the section of the pipe that is leaking. Clean the ends of the remaining pipe with sandpaper and apply flux to the cleaned areas. Next, fit a new piece of copper pipe into the gap and use a propane torch to heat the joint. Once the joint is hot enough, apply solder around the joint, allowing it to flow into the joint and create a watertight seal. Finally, allow the joint to cool and then turn the water supply back on to test for leaks. **

No, it is not allowed to soft solder copper when it is hot. Soft soldering requires the copper to be at room temperature in order for the solder to properly adhere to the surface. Attempting to solder copper while it is hot can result in poor adhesion and a weak bond between the solder and the copper. It is important to allow the copper to cool down before attempting to soft solder it. **

Oxygen-silver solder and copper are referred to as elements because they are both pure substances that cannot be broken down into simpler substances by chemical means. In the case of oxygen-silver solder, it is a mixture of oxygen and silver, both of which are elements. Copper, on the other hand, is a single element with its own unique set of chemical and physical properties. Therefore, both oxygen-silver solder and copper are classified as elements due to their pure and unbreakable nature. **

The durability of solder joints in copper pipe water lines is generally very high. When properly installed, soldered joints can last for decades without any issues. However, the durability of the solder joint can be affected by factors such as water quality, water pressure, and the quality of the soldering work. It is important to ensure that the joints are properly cleaned, fluxed, and soldered to maximize their durability. Regular maintenance and inspection of the solder joints can also help identify and address any potential issues before they become major problems. **
