Quick Summary

Filler metal is a material used in joining metals, such as in brazing or welding. In brazing, a filler metal with a lower melting point than the base metals is used to create a bond when heated above 800°F (430°C). In welding, filler material can be added to the molten pool of base metal to form the weld. The composition and properties of the weld metal, which is the fused part of the joint, are crucial for the joint's performance. Powder metallurgy is another method of fabricating metal objects, where metal powders are compressed and then heated below their melting point to form a solid object.1234
