The main purpose of brazing in metalworking is to connect two metals at elevated temperatures typically above 800°F, using a non-ferrous filler material. This process involves melting the filler metal, which then flows into the joint between the two base metals through capillary action, forming a strong bond upon cooling. The use of a non-ferrous filler differentiates brazing from other joining methods, such as welding or soldering, where different materials and temperatures are applied. This high-temperature joining process is essential for applications requiring strength and durability, making it suitable for various industrial usages. The capability to bond dissimilar metals is another advantage that distinguishes brazing, offering versatility in fabrication processes.
