Which application is most suitable for brazed joints rather than welded joints in industrial manufacturing?
Brazed joints are ideal for joining thin-walled copper tubes.
Brazing joins metals with a filler that melts below the melting point of the base metals, so the parts themselves are not melted.
This makes it ideal for thin, heat-sensitive parts and for good conductors like copper: thin-walled copper tubes can be joined without burning through or distorting, and the joint is leak-tight, which is why brazing is standard for copper pipework.
Thick or heavy steel, aluminium and large cast iron sections need the deep, strong fusion that welding provides, so brazing is less suitable there.
Hence, brazed joints are most suitable for joining thin-walled copper tubes.
