basics of Soldering Brass
Brass is the alloy formed by mixing any
proportions of copper and zinc. The proportions
are varied for the material properties needed.
is easily soldered and so does Brass if you use
the right flux and have the right heat.
flux is used to removed the oxide and allow the
solder to bond into the material and link two
pieces together. You can if the part are very
small small use electrical "cored solder" with the
flux being in the cores but larger pieces are
better soldered using the type of flux used in
plumbing and a micro point butane torch as the
is best to practice soldering on scrap pieces of
metal similar to those of the finished item to get
a feel of the technique to be used. It is not
impossible to heat up the brass to such and extent
that it melts!
too much heat can result in the flux just being
burned off, or too little heat and the flux never
reaches a suitable temperature - in both cases a
satisfactory joint cannot be made.
amount of flux to be applied to the joint before
assembly is depended upon the flux being used and
thus the instructions must be read and followed.
heat the part until you see a reaction taking
place which is the flux doing its job. Introduce
the solder to the metal and NOT TO the flame and
when it is at the right temperature is will flow
easily - too easily at times, when the metal is
too hot and run out of the joint ; so make sure
that the surface you are working on is fire
Always carry out the soldering in a
well ventilated room and avoid inhaling any of
the fumes given off by the process. Wash away
any spills especially if in contact with your
skin and ALWAYS follow the direction on the
containers of flux and solder.
