The welder must also keep the filler metal in the hot outer flame zone when not adding it to the puddle to protect filler metal from oxidation.

Soldering differs from gluing significantly in that the filler metals alloy with the workpiece at the junction to form a gas-and liquid-tight bond.

The American welding society defines brazing as using filler metals with melting points over or, by the traditional definition in the United States, above.

Brazing is another heat-treating process used to join two or more base metal components by melting a thin layer of filler metal in the space between them.

The buttered layer can be the same alloy as the filler metal or a different filler metal that will act as a buffer between the two metals to be joined.

"Brazing " is a joining process in which a filler metal is melted and drawn into a capillary formed by the assembly of two or more work pieces.
39.
Since the joint is produced using a metal with a lower melting temperature than the workpiece, the joint will weaken as the ambient temperature approaches the melting point of the filler metal.
40.
Ultrasonic welding uses ultrasonic energy to join parts without adding any kind of filler material while ordinary soldering uses external heating to melt filler metal materials, namely solders, to form a joint.
