Abstract

A study was conducted for the applicability of a 250kV ultra high voltage electron beam of an ultra high energy density heat source to the flat position full penetration welding of 12.8mm thick plates of 18%Ni maraging steel (HT 210). It was verified that this ultra high voltage welding was advantageous to the production of a sound narrow weld bead without weld defects such as porosity, etc. Moreover, investigation of the effect of heat treatments on the mechanical properties of electron beam weld metals revealed an optimum combination of both homogenization and grain-refining solution heat treatments to achieve the highest hardness, strength and fracture toughness of the weld metals.
