What is sautering?

Soldering is a joining process that involves melting a filler metal and flowing it into the joint between two pieces of material. The filler metal, called solder, is typically a metal alloy with a lower melting point than the materials being joined. The aim of soldering is to create a permanent joint that is strong, reliable, and has good electrical and thermal conductivity. Some common applications of soldering include plumbing, electronics, jewelry making, and metalwork. Soldering can be done using a wide range of tools and techniques, from simple hand-held tools, to more complex soldering stations and automated machinery. There are also different types of soldering, such as soft soldering, hard soldering, and brazing, which are used in different applications depending on the strength and temperature requirements of the joint.
