DEVELOPMENT OF PROCEDURES FOR WELDING 2-INCH-THICK TITANIUM-ALLOY PLATE
Abstract
Lehigh and NRL restraint tests were made on Ti13V-11Cr-3Al alloy plate with filler wire that matched the composition of the base plate. No cracking was encountered in these welds. In addition, a 30-in.-long weld was made in 2in.-thick Ti-13V-11Cr-3Al plate with filler wire that matched the composition of the base plate. Weld-metal ultimate and yield strengths were somewhat lower than those of the base plate. Elongation of the weld metal was higher than that of the base plate in the transverse direction but lower than that of the base plate in the longitudinal direction. Impact properties of the weld metal were very low, but were similar to those of the base plate. Hardness data obtained for welds in Ti-6Al-4V base plate with Ti-6Al high-purity filler wire were lower than for any weld except those made with A-55 filler wire. Vacuum-fusion analysis of this weld showed very low O and H contents.
