Filler Wire

Filler wire, also known as filler metal, is a type of material used in welding to join two pieces of metal together. The filler wire is typically made of the same or similar metal as the base metal being welded and is used to add material to the weld joint. This is done by melting the filler wire and fusing it with the base metal to form a strong bond.

Filler wire is available in many different materials, including steel, stainless steel, aluminum, and nickel alloys. The size and composition of the filler wire depend on the type of welding process being used, the base metal being welded, and the desired strength and properties of the finished weld.

Filler wire is used in various welding processes such as Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), and Shielded Metal Arc Welding (SMAW). It is available in various diameters, and it can be used in both manual and automated welding processes.

In summary, filler wire is a crucial component in welding as it provides the material needed to join two metal parts together to form a strong bond.
