Filler Wire

A Filler Wire, also known as Welding Wire, is a thin metal rod that is ignited to produce a heated arc for the purpose of fusing together metal parts (welding) by rendering the wire soft by hammering or compressing under the applied heat source.


Filler wire is commercially available in a broad range of forms and classifications. Different welding jobs and base metal products need an appropriate welding wire to be used for the application. These Filler Wires are also available in a number of materials. It is important to select the right material for a given workpiece.


Filler wires are gas-shielded electrodes with a wide range of mechanical characteristics, arc behaviour, quality and cost. There are three main types of welding wires:

  1. Solid gas metal arc welding (GMAW) wire.
  2. Composite GMAW (metal-cored) wire.
  3. Gas-shielded flux-cored arc welding (FCAW) wire.


Once the suitable wire type is selected, it is important to choose the correct wire diameter and chemistry for the application. These are available in stainless steel, nickel, high nickel-based alloys, and special-purpose welding wire.


Fillers Wires are used in applications like Tank Fabrication, Overlay/Cladding, Chemical Processing, Pipes, Hydro Turbines, Mufflers, Pumps and Valves in various application industries like Oil and Gas, Food and Beverage, Automotive, Energy, Nuclear, Defense, Construction, and Marine applications.
