The principle of welding, how to form the solder joint
The principle of welding is based on solid bonding between metals, and the specific formation process involves several key aspects. First, the metal at the connection site is heated to a molten state, which is called melting core. When the temperature is high enough, the surface tension of the material being welded is reduced, allowing the molten metal (solder) to wet the substrate and solidify to form a strong contact as the temperature decreases.
