Laser Butt Welding of Thin Ti6Al4V Sheets: Effects of Welding Parameters

Titanium and its alloys, particularly Ti6Al4V, which is widely utilized in the marine aerospace industries, have played a vital role different manufacturing industries. An efficient cost-effective way of joining this metal by laser welding. The effect power welding speed on tensile, microhardness, microstructure Ti6Al4V alloy investigated paper. Results show that microhardness highest at fusion zone reduces towards base metal. shows transformed needle-like lamellar α phase, with martensitic α’ phase observed within heat affected zone. tensile tests an improved strength compared to
