Filler metal is added to the joint in welding,brazing and soldering.
it is added to supply the material to the joint or to improve the propoties of the joint.
in soldering lead-tin solder alloy is used in soft soldering.
Filler alloys/metals have lower melting point than the parent metals.for complex shapes like jewellary it is soldered in stages to improve the joint propoties.
