Abstract : Procedures for welding 2-inch-thick Ti-alloy plate were developed for 4 alloys: commercially pure titanium, Ti-6Al-4V, Ti-5Al-2.5Sn, and Ti-13V-11Cr-3Al. Commercially available filler wires and experimental filler materials were used make the welds. The properties of the welds were generally as good as or better than those of the base plate. The results show that heavy titanium-alloy plates can be satisfactorily welded provided they are adequately protected from weld contamination and the compositions of the filler wire and base plate are properly controlled. A controlled-atmosphere welding chamber was used to provide protection for the welds in this program. The impact properties of the base plate did not meet the requirements for submarine hulls, but two of the alloys show promise: Ti-6Al-4V and the Ti-5Al-2.5Sn alloys. (Author)
