Weld cracking tests were made and the properties of welds in 2-in.- thick A-70 base plate were obtained for welds made with A-55 filler wire. The impact properties for the weld made in A-70 base plate were about 5 ft-lb higher than those of the base metal, and the weld-metal yield strength was about 11, 000 psi lower than that of the base plate. In the weld made in Ti-6Al-4V plate with Ti-5Al-2.5Sn filler wire, the notch toughness and yield strength were similar to those of welds made with Ti-6Al-4V filler wire however, the ductility of the weld made with the Ti-5Al-2.5Sn filler wire was considerably higher. In the weld made in Ti-6Al-4V with A-55 filler wire, the notch toughness was better than that of the weld made with matching filler wire. However, the strength of the weld made with A-55 filler wire was low and transverse tension specimens failed in the weld metal at a joint efficiency of only 75.
