The laser brazing process uses a filler metal for joining without actually melting the base material. Brittle metals, such as cast iron, can be welded without preheating too much. Typically, braze welding is used on steel and cast iron, but copper, nickel, and nickel alloys are also welded by this method. it can be weld to dissimilar metal, cast metal and ferrous metal. Braze welding process is a method of joining materials together where a non-ferrous filler metal with a melting point, below that of the base metal but above (427 0C )is used. Preheating of the part to be brazed are usually 425 0 C to 480 0 C. In braze welding, less heat is required resulting in less distortion than in conventional welding. Brass brazing alloys can be used for brazing and for the Oxy-Fuel Gas Braze-Welding process, with liquid flux spread through the torch flame. Properly brazed joints are stronger than either base metal, but not as strong as welded joints. Brazing is a widely used joining process because it can join almost all metal except aluminium and magnesium. (Sept. 23, 2013) http://www.aws.org/bsmc/wj200810_39.pdf, Lucas-Milhaupt.

By this process, a groove fillet plug or slot weld can be welded easily. Brazing associated with melting of a relatively low melting point filler material, being distributed by capillary attraction whereas braze welding is normally employed for welding grove, plug slot and fillet welds. Enter your email address to subscribe to this blog and receive notifications of new posts by email. A slightly oxidizing flame is used in braze-welding and bronze-surfacing while a more strongly oxidizing flame is used in fusion welding certain brasses and bronzes The size of the flame can be adjusted to a limited extent by the valves on the torch and by the regulator settings, but in the main it depends on the size of the orifice in the tip. The American Welder. Welding, on the other hand, doesn't rely on large-scale heating. It is used for electrical components, pipe fittings.
