[0002] Refrigeration equipment needs to be repaired and maintained during operation, and one of the key processes is welding. Welding is the process of melting two or more metal parts by heating and forming a strong connection during cooling. In order to ensure the quality and reliability of welding, it is crucial to choose suitable welding materials. In the welding process of refrigeration equipment, a commonly used welding material is silver brazing. Silver brazing is a welding material with silver and its alloys as the main components. It has good thermal conductivity, electrical conductivity and corrosion resistance. It is suitable for welding in high temperature environments. Silver and its alloys often need to be melted and extracted using a furnace.
