Soldering is a process of joining two or more metal parts using molten metal (solder) by heating. Soldering is commonly used to join electronics and electrical components. During soldering, the solder melts and penetrates the metal, creating a strong mechanical and electrical connection. A soldering iron or tool is used to solder, which is heated and melts the solder. Solder metal is usually a mixture of lead and tin, or nowadays, lead-free solder is used, which is environmentally friendly.
Maintaining the correct temperature while soldering is very important, because if it is too hot, the parts can be damaged, and if it is too cold, the solder will not melt properly and the connection will not be formed. Soldering skills increase the durability and functionality of electronic components. It is a simple, fast, and affordable method that is widely used from home to large industrial organizations. It is possible to repair, create, and improve electronic circuits by learning soldering.
