Abstract: Single melt titanium alloy is being considered for use as armor in ground combat vehicles due to its lower cost relative to aerospace-grade material. This report examines welding issues associated with fabricating titanium alloy plate. In particular, the quality of welded single melt material was investigated as well as the possibility of out-of-position welding of standard titanium alloy. The initial results indicate that single melt material can be welded using standard techniques. Out-of-position welding can be accomplished under controlled conditions, but further process development would be needed to be able to repair titanium alloy armor in the field.
