Exothermic Brazing

Exothermic brazing is yet another brazing process which depends on the heat source to melt down & flow the commercial filler which is generated by the reaction of many solid state exothermic chemical compounds.

This particular exothermic chemical reaction has its own definition which one must understand for a greater knowledge about Exothermic brazing. This reaction is just like nay other reaction which occurs between two or more reactants where the system's free energy helps in giving away the heat. These reactions are caused with solid state or solid-state-metal-metal-oxide. These are one among the many & countless reactions available in nature. Perfect for use in exothermic brazing units, these even make use of simplified tooling and equipment.

Heating of Exothermic Mixture
Exothermic mixture is ignited with the help of either of the following :

• Flame
• Hot Spark
• Resistance Heater

Infrared Brazing Process
The process employed in the particular brazing method allows the reaction of heat which helps in bringing the adjoining or nearby metal interfaces to a certain temperature. At this point, the preplaced brazing filler metal melts and wets the metal interface surfaces. There is commercial availability of brazing filler metal made as per the requirements of the varied melting and flow temperatures. The only drawback of this brazing method is the metal thickness which should be heated through, thereupon, leaving an effect on the metal properties.
