Brazing is a process of joining two pieces of metal, in which both filler material and the parent metal are heated up, and the filler material melt into a liquid state between the pieces of parent metal.
Paste is the most common type of brazing material, which is mainly mixure of metal powder and organic solvent.
Amorphous brazing foil is a new type of brazing material.
The function of brazing “stop-off” is supposed to “stops” molten brazing filler metal from flowing into areas where it is not supposed to be, thus keeping it “off” surfaces that are supposed to remain clean.
