Brazing example for DetoxGuru.

Brazing example for DetoxGuru. Tube. Duration : 2.78 Mins.


Quick wee video to let DetoxGuru see what Brazing involves. Brazing is a metal-joining process whereby a filler metal or alloy is heated to melting temperature above 450 °C (840 °F) and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere or flux. It then interacts with a thin layer of the base metal (known as wetting) and is then cooled rapidly to form a sealed joint. By definition the melting temperature of the braze alloy is lower (sometimes substantially) than the melting temperature of the materials being joined. Brazed joints are generally stronger than the individual filler metals used due to the geometry of the joint as well as to the metallurgical bonding that occurs. For what you're wanting to do, you should get silver brazing rod. Many silver rods come with flux already on them, so scrub your joints with a wire brush until the joints are shiny, then braze away. Good luck dude.
