Weld metal is the material that has melted and re-solidified as a result of the welding operation. In cases where no filler material is added (resistance, electron beam, laser and some autogenous arc welding), the weld metal has the same composition as the parent material. Where filler materials are added to the weld pool, the composition of the weld metal usually differs from that of the parent material.“
