DEVELOPMENT OF PROCEDURES FOR WELDING 2-INCH-THICK TITANIUM-ALLOY PLATE

Abstract

Three experimental filler materials were ma e and eposite in Ti-6Al-4V plate to obtain weld metals with high-impact proper ies. Weld metals ade with one of the experimental filler materials (Ti-5Al-2Cb-1Ta) had the highest impact properties of any weld or base plate evaluated in his program. The impact properties were 50 ft-lb at room temperature a d 44 ft-lb at -80 F. The yield strength of the weld made with this filler was 104,000 psi. The impact properties of the welds made with the other 2 experimental fillers (Ti-6Al and Ti-6Al-4V) were higher than the impact properties of the welds made with comm rcial filler wire . T e exp rimenal fillers contained rel tively low O contents n the wel s made with these fillers contained considerably less O tha the welds made with the commercial filler wire. Cracks were observ d in a multipass T I-%Al-2.5Sn weld made with matching filler wire. (Author)
