Compact Ignition Tokamak (CIT) vacuum vessel welded joint R and D: FY-87 final report

The general purpose of the vacuum vessel welded joint research and development program for FY-87 was to begin the development of both an optimum welded joint design and an analytical method for predicting joint distortion. This work was divided into three subtasks: weld joint tests, to develop automatic welding parameters and producing reliably strong, low distortion joints; material tests, to assess the long term reliability of the welded joints by means of metallographic examinations and fatigue tests; and weld joint analysis, to develop a reliable general method to analytically predict weld joint distortion. 2 refs., 8 figs.
