Current Research Situation and Prospect of Wire and Arc Additive Manufacturing of Titanium Alloy

Abstract

Wire arc additive manufacturing is an important part of additive manufacturing. Because of its low processing cost, high forming efficiency, high material utilization rate and low equipment cost, it is favored in the fields of medical and aerospace. This paper briefly discuss the technologies of titanium alloy wire arc additive manufacturing. The influence of different deposited parameters, interpass rolling, ultrasonic assistance and heat treatment on the forming quality of titanium alloy wire arc additive components are summarized and analyzed. Finally, combined with the actual engineering requirements, the problems and research directions of the development of titanium alloy additive manufacturing are analyzed.
