Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
Traditional techniques involve cutting out copper sheet to form the sidewall forming it to cylindrical shape and making a joint.
Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves.
Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel.
Brazing takes place above 840 degrees f but below the melting point of the base metal source.
Quick and easy brazing aluminum copper and nonferrous metals.
Nickel silver brazing welding rods.
The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch.
Brazing is also much easier then welding it s a lot like using a glue gun.
As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature.
The corresponding uns numbers are shown in table 5.
Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.
The filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting.
Cu ni alloys are most often brazed with silver base brazing alloys.
Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance.
