Brazing holds a significant advantage when joining dissimilar metals. These can form a strong joint with minimal alteration of basemetal properties, provided the filler material is metallurgically compatible with both base metals and has a melting point lower than the two.
What is brazing used to join?
Brazing joins two metals by heating and melting a filler (alloy) that bonds to the two pieces of metal and joins them. The filler obviously must have a melting temperature below that of the metal pieces. Brazing can join dissimilar metals such as aluminum, silver, copper, gold, and nickel.
Where do you use brazing rods?
Apply the brazing rod to the joint while continuing to heat the metal surfaces. For large areas, heat portions of the joint to temperature and then move to the next adjacent area. After brazing, use a wire brush to clean the brazed surface to remove any oxidation or residue.
