Soldering with soldering depot
Soldering is the process of joining together 2 or more metals using another molten metal that has a lower melting point than the metals being joined. Soldering with soldering depot involves use of filler metal that is put between the two metals. The soldering depot is usually fusible metal alloy whose melting point ranges between 90°C and 450 °C. When the depot is placed between two already heated surfaces, it melts down to create a joint that binds the metals. When soldering with soldering depot the most commonly used material is lead and flux although there are instances where lead-free depots are used.
