The present invention provides an apparatus for hardening a metal article, comprising a holding device, an energy beam generator pointed at the holding device for directing energy beams at the holding device, and an auxliary heating device engaging the holding device, wherein the auxiliary heating device heats the metal article independently from the energy beam. The apparatus includes an energy beam delivery instrument system positioned between the energy beam generator and the holding device so that the energy an energy beam delivery instrument directs the energy beam to the holding device. Also, the apparatus also includes a transport system supporting the holding device, wherein the transport system varies the location of the holding device relative to the energy beam generator.
