Brazing

Brazing is a manufacturing process that can be applied when using a carbide ball and stainless steel wire.  This is a soldering technique that joins the two materials, but is called brazing when the temperatures are above (842 degree F/450 degrees C).  Brazing is a metal-joining process whereby a filler metal is heated above melting point and distributed between two or more close-fitting parts by capillary action.  The filler metal is brought slightly above its melting temperature.  It then flows over the base metal and then cooled to join the work pieces together.

The critical part of this manufacturing process is to ensure that two pieces are free of contaminants and the surfaces match up as closely as possible while also maintaining the proper temperature to melt the filler (i.e. solder).  Maintaining these three critical parameters makes the ball and wire joint stronger than the original materials.
