摘要

A study was conducted to develop electron-beam-welding procedures for several grades of beryllium 1/16to 3/4inch thick,using a 9kw, 30kv electron-beam welder. Weld quality was enhanced by low beryllium oxide content in the base metal and a minimum welding-energy input. High travel speeds created undesirable fusion-zone grain structures. (Author)
