This document compares brazing and soldering processes. Brazing involves joining metals using a filler metal or alloy that melts above 840°F but below the melting points of the base metals. It provides a strong bond and can join dissimilar metals, but the equipment and filler metals required make it more expensive than soldering. Soldering uses alloys that melt below 840°F to join metal works, making it cheaper and suitable for electronics work, but the lower temperatures result in weaker joints than brazing.
