Copper is used for soldering iron tips because it has good thermal conductivity, allowing it to quickly transfer heat from the iron to the soldered joint. Additionally, copper is durable and resistant to corrosion, making it suitable for prolonged use in soldering applications.
The type of material used to connect the pieces. Solder is used on copper or brass. Brazing uses a copper alloy and is used on Iron based items. Same process in how it is done.
You don't glue it, you sweat them. That is the term used for soldering them together.
It melts solder. Solder was originally a mix of lead and tin that was used to join copper to copper (pipes and wiring) It is in the shape of a pistol, but does not shoot anything.
Copper is used because it is a good conductor of heat and thus more energy efficient. The solder melts at a temperature lower than copper and the soldering iron is controlled to only reach a high enough temperature to melt the solder. There are metals that are more efficient at conducting heat, But considering the melting point of copper, it high availability and relative cost. Copper is by far the obvious choice to use in a soldering iron.
Soldering can be used to make a reliable connection between two pieces of copper wire that is less likely to develop a fault than other ways of making the connection.
Soldering wire is usually made of a combination of tin and lead. The most common ratio is 60% tin and 40% lead. However, due to environmental and health concerns, lead-free solder wire made of tin, silver, and copper is also widely used now.
A soldering stand is a device used to hold a soldering iron securely when it's not in use, preventing it from causing burns or fires. It typically features a heat-resistant base and may include additional features like a sponge for cleaning the soldering tip. Soldering stands help ensure safety and efficiency while working on electronic components or circuit boards.
Copper pipe brazing involves melting a filler metal with a higher melting point than solder, creating a stronger bond. Soldering uses a lower melting point filler metal, creating a less strong bond. Brazing requires higher temperatures and is typically used for larger pipes or high-pressure systems, while soldering is used for smaller pipes or low-pressure systems.
A soldering iron stand is used to safely hold a hot soldering iron when it's not in use. This prevents accidental burns or damage to surfaces and tools, as the soldering iron can reach very high temperatures. The stand often includes a sponge or brass wool for cleaning the soldering iron tip, ensuring optimal performance and longevity. Additionally, some stands come with features like adjustable heights or built-in storage for soldering supplies.
Brazing and soldering are both methods used to join copper pipes, but they differ in the temperatures at which they are performed. Brazing involves higher temperatures and the use of a filler metal with a melting point above 840F, while soldering is done at lower temperatures using a filler metal with a melting point below 840F. Brazing creates a stronger bond than soldering, making it more suitable for high-pressure applications.
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
