A review on welding and fatigue behaviour of titanium and its alloys

Abstract

Titanium is metal element which comprises about 0.44% of earth's crust. The abundance and reliable properties of this element made it essential in field of engineering works. Welding is a fabrication process which fuse the materials together. Welding of titanium and its alloys expands the applications of usage of titanium. The idea of this review, is to sum up the welding and fatigue behavior of titanium and its alloys. It has been identified that laser beam welding (LBW) is feasible for titanium and its alloys due to its flexibility, high heat capacity input and efficiency.
