A brazing torch is a specialized thermal tool used to join two or more metal pieces together by melting a filler metal with a lower melting point than the base materials, typically above 450°C (840°F). Unlike welding, which melts the parent metals to fuse them, or soldering, which operates at lower temperatures with weaker joints, brazing creates a strong, durable, capillary-action bond without altering the structural integrity of the base metals.
Below is a comprehensive guide to understanding brazing torches, covering their types, fuel sources, operational steps, applications, and safety practices.
