Abstract : Various welding practices were evaluated by bend, smooth and notched (Ksub t=8) tensile, and tensile Gsub c testing. In addition, a cyclic test technique was developed which simulated the stresses welds would be subjected to during hydrostatic pressure testing. This technique was used to investigate the tendency for the welds to crack through porosity. The various welding practices included electron beam welding and single and multipass TIG welding using various filler materials and welding fixturing. Electron beam welding did not produce a significant improvement in weld toughness and had many disadvantages for the intended application. (Author)
