Hitsauskolvit

Hitsauskolvi, commonly known as a soldering iron in English, is a tool used for soldering. Soldering is a process that joins metal surfaces by melting filler metal (solder) with a heated tool. The heated tip of the soldering iron melts the solder, which then flows into the joint between the surfaces to be joined. This molten solder solidifies upon cooling, creating a strong electrical and mechanical bond.

Soldering irons consist of a heated metal tip, a heating element, and a handle. The heating element, typically a resistive wire, heats the tip to temperatures ranging from 150°C to 450°C, depending on the application. The handle is usually made of heat-resistant material to protect the user from the heat. Different tip shapes and sizes are available, such as conical, chisel, and knife tips, each suited for specific soldering tasks.

Soldering irons are widely used in electronics for assembling and repairing printed circuit boards (PCBs), connecting wires, and attaching components. They are also employed in other applications like jewelry making, metal art, and stained glass work. The type of soldering iron chosen depends on the required heat output, precision, and the materials being soldered. Temperature-controlled soldering irons offer greater accuracy and are preferred for delicate electronic work.
