TWI Frequently asked questions
Brazing and soldering - what's the difference?
Brazing and soldering are in essence very similar in that a filler metal (the braze or solder) is melted between the two components to be joined. The distinction between the two processes arises from the temperature at which the filler melts; brazes melt above 450°C, solders melt below 450°C.Copyright 2000, TWI Ltd
