What is Soldering?

What is soldering? Soldering is a process of joining two or more different types of metal together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong and durable joint. Why do we use it? It is inexpensive, fairly easy to learn and do. It is also a quick process. 

Plumbing, roofing, electronics - making electrical connections between components 

These are parts of a soldering iron - all soldering irons are similar. These are the main parts. Always hold it by the handle, not on the silvery metal part. The metal part, especially the tip, can reach temperatures of almost 600 degrees F. Keep the tip clean at all times. We will talk about how later in the presentation. Make sure that the electric source is close to the work area and the cord is not spanning across a walk through 

The stand is mainly to keep the hot tip of the soldering iron from touching the table or burning something between uses and during heating up and cooling down times. When not in use, rest the iron in/on the stand. These may also get hot due to heat conduction. Allow to cool before handling 

The brass wire and damp sponge are two methods of cleaning the tip of the iron while working. Clean the tip regularly by wiping it on the damp sponge or against the brass wire. This will help the iron transfer heat and maximize the tip’s lifespan. 

Solder wire comes in different thicknesses and compositions. Make sure you get the lead-free solder. Just in case, wash your hands after handling solder. Most new solder is now lead free due to the toxic nature of lead. 

Some additional tools are handy and sometimes necessary when soldering: The wire stripper is used to remove insulation from the wire of different thicknesses. The wire cutter or diagonal cutting pliers are helpful in trimming excess wire at connections. These tools are sharp and need to be kept that way. The fulcrum of each needs to be oiled occasionally to ensure they work well 

The solder sucker or desoldering pump is used to remove unwanted solder from a connection. When the solder is hot and liquid, this is used to remove it from the connection. Remember, this is molten metal and so you do NOT want to use your fingers to remove hot solder 

Safety glasses are an important piece of equipment when working with tools. Little pieces of solder or wire are sharp and can cause permanent damage to your eyes if they get in there. Wear them while soldering. 

Ventilation while soldering is important as fumes are emitted from the flux in the solder. These can be harmful and cause respiratory problems. It is best to solder near an open window, using a local ventilation system, or position yourself so you are not in the path of the rising fumes.
