Brazing

Brazing is a group of welding processes, which produces, coalescence of materials by heating them to a specific temperature and by using a filler metal having a liquids above 450 °C and below the solids of the base materials. The filler metal is distributed b/w the closely fitted surfaces of the joint by capillary attraction. A braze is a special type of weld, the base metal is theoretically not melted. Some of the popular brazing methods are:

• 1. Diffusion brazing
• 2. Dip brazing
• 3. Furnace brazing
• 4. Induction brazing 
• 5. Infrared brazing
• 6. Resistance brazing
• 7. Torch brazing.
