A study was undertaken to investigate the feasibility of using a high power electron beam welding machine to weld heavy section steel of three different compositions. These were 3 Cr-1.5 Mo-0.1 V, 2.25 Cr-1 Mo, and modified 9 Cr-1 Mo steels. Emphasis in this work was placed on determining the mechanical properties of the weldments, characterizing the microstructure of the various weldment regions, and comparing these results with those from other welding processes. Characterization of the electron beam weldments was made by microhardness measurements, Charpy V-notch impact tests, tensile tests, and guided bend tests. The testing results showed the electron beam weldments had excellent properties which makes it an attractive process for heavy section steel welding.
