Wire arc additive manufacturing technology development and route planning map for aviation equipment

Abstract

Wire arc additive manufacturing (WAAM) is an additive manufacturing technology with high deposition rate that produces a variety of high-performance metal structures layer by layer stacking. The research on WAAM technology of large and medium complex aluminum alloy and titanium alloy for aviation equipments has been widely concerned. In this paper, the WAAM technical definition, classification, forming system and principle are discussed. The recent research progress in the microstructure properties, metallurgical defects, quality improvement and technical application of typical components of aluminum alloy and titanium alloy formed by WAAM in aerospace field both at home and abroad is reviewed. The key common problems in the WAAM forming large and medium complex components of aviation equipments are analyzed, and the 2035 WAAM forming technology route planning map is proposed. In 2035, the "shape control" and "property control" technology of WAAM aluminum alloy and titanium alloy component is to be mastered; the large and medium complex structure components of aluminum alloy and titanium alloy which formed by WAAM are achieved comprehensive application in aviation equipment.
