Experimental Study on Welding Process of TC4 Titanium Alloy with Different Welding Wires

Abstract:

In present study, the effects of different welding wires on the evolution of microstructure and mechanical properties of TC4 titanium alloy test plates were studied. The results show that the test plates welded by TA20 titanium alloy wire, TC3 titanium alloy wire and TC4 titanium alloy wire are well formed, no defects are found in the cross section of the weld. The microstructures of these test plates are similar, and needle-like martensite exists in the weld area. In comparison, this is little obvious difference in tensile strength among these test plates welded by different welding wires, while the plates welded by TC4 titanium alloy has better elongation, contraction of aera, impact toughness and better balance of strength and toughness.
