PRODUCTION AND INVESTIGATION OF WELDABILITY OF ONE-INCH THICK TITANIUM 6AL-4V PLATE.

Abstract

One-in-thick Ti-6Al-4V plate was produced having good strength and a surface case of fine grained metal. Five groups of welded plates were evaluated by tensile and impact tests. The welds were deposited with Ti-6Al-4V filler wire, Ti-5Al-2.5Sn filler wire, MST 55 filler wire, MST 40 filler for root passes, Ti-6Al-4V filler for central and cover passes, MST 40 filler for root and cover passes, and Ti-6Al-4V filler for central passes. Test results indicated that welds made with Ti-5Al-2.5Sn filler wire had the best combination of strength and ductility. Three welded plates for each of the 5 groups and 3 unwelded plates will be tested by explosion crack-starter and drop-weight tests. (Author)
