Copper: Copper Tube Handbook: VII. Soldered Joints
7. Soldered Joints. The American Welding Society defines soldering as "a group of joining processes that produce coalescence of materials by heating them to a soldering temperature and by using a filler metal (solder) having a liquidus not exceeding 840°F and below the solidus of the base metals." In actual practice, most soldering is done at ...

Copper in Your Home: Do It Yourself
Clean the fitting cups by using abrasive cloth, abrasive pads or a properly sized fitting brush. The capillary space between tube and fitting is approximately 0.004 in. Solder metal fills this gap by capillary action. This spacing is critical for the solder metal to flow into the gap and form a strong joint.

What are the Different Types of Solder?
Ans: The three main types of solder are lead-free solder, lead-based solder, and flux-core solders. There is another type known as silver alloy solder. These types are made on the composition of alloys. Apart from this, there are other solder types depending on the form, core style, and application. 2.

The temperature must be hot enough to melt the solder but not too hot that it causes damage to the materials being joined. Using a temperature-controlled tool like a soldering iron or torch can help regulate the heat and prevent any mishaps.Can you solder copper?
What are the challenges when soldering copper?Another challenge when soldering copper is its oxide layer. When exposed to air, copper reacts and forms a layer of oxide on its surface that can prevent the solder from sticking to the copper. This layer can also cause the joint to become weak and brittle over time.Can you solder copper?
