Brazing

« Back to Glossary Index

A method of joining two or more metals by melting a filler material (often called a brazing alloy), which flows into the joint by capillary action. The filler material has a melting point above 840°F (450°C) but below the melting point of the base metals being joined, which remain solid throughout the process. The process requires heating the area with a brazing torch, furnace, or other heat sources to ensure the filler flows evenly and creates a strong, sealed bond. In HVAC systems, brazing is commonly used to connect copper pipes and components, such as refrigerant lines, ensuring airtight and leak-free connections critical to system reliability
