A type of metal sometimes added to the joint in fusion welding. Filler metal adds to the strength and mass of the welded joint.
Metal added in making a welded, brazed, or soldered joint.
Metal, which is added to be used to bond materials being welded, brazed or soldered and which fills in the gaps in the joints of the metal.
A filler metal is a metal added in the making of a joint through welding, brazing, or soldering. Four types of filler metals exist—covered electrodes, bare electrode wire or rod, tubular electrode wire and welding fluxes. Sometimes nonconsumable electrodes are included as well, but since these metals are not consumed by the welding process, they are normally excluded.
