Brazing Rod & Other Brazing Filler Metal
Brazing, or braze welding, is a metal-joining process in which a filler metal is heated above melting point and distributed between two or more close-fitting parts by capillary action to braze a joint or fill a hole. The filler metal—typically in the form of brazing rod (see below)—is brought slightly above its melting temperature while protected by a suitable, often artificial, atmosphere, usually a flux. The melted brazing rod flows over the base metal (a process known as wetting) and is then cooled to form a joint between the workpieces.
Metal brazing is similar to soft soldering (using tin/lead alloys), except the temperatures used to melt brazing filler metals are higher—generally above 800°F (427°C)—though the required temperature depends on the brazing alloy being used.

Braze Welding Methods
Many different heating methods can be employed in brazing. The most important factor in choosing a heating method is achieving efficient transfer of heat throughout the joint and doing so within the heat capacity of the individual base metals used. The geometry of the braze joint is also a crucial factor to consider, as are the rate and volume of production required.
The easiest way to categorize metal brazing processes is to group them by heating method. Some of the most common brazing processes are:
- Torch Brazing
- Furnace Brazing
- Induction Brazing
- Dip Brazing
- Resistance brazing
- Infrared brazing
- Blanket brazing
- Electron beam and laser brazing
