【 摘 要 】

The welding of beryllium has been a problem of interest to Los Alamos National Laboratory. Considerable effort has been expended in the modeling of such welds, with the intended outlook being the fabrication of a superior bond between beryllium pieces through an optimization of weld parameter, e.g., amount of pre-heat and the times needed for melting and solidification.
