Recently electron beam welding process is often used for precise welding processes because of the feature that there is less distortion than other conventional fusion welding processes. Therefore it is believed that the studies of weld distortion on welded joints by this process is important. For this reason the authors researched the thermal distortion of welded joints shaped as a disk or a ring which were welded concentrically in various conditions of welding heat input and plate thickness. In a part of the research on distortion, the angular change was obtained by measuring the two marked points which were set on both sides of the weld seam before welding. The authors evaluated the angular change by using the parameter which was determined by accelerating voltage, beam current, welding speed and plate thickness.
