Abstract
Wire arc additive manufacturing (WAAM) technology has received increasing attention because of its high forming speed,flexible forming size,in particular,the large-size complex shape of the efficient shape of the rapid molding,wire and arc material has its unique advantages This paper introduced the technology of WAAM,reviewed the current research situation both at home and abroad from forming process and surface quality of the forming material,the microstructure and properties of the forming part and the residual stress of the forming part three aspects,and then summarized its application in the aerospace field,pointed out that present research work of WAAM mainly focused on the process optimization and process control.How to get the high quality parts by means of smoothly transfer of droplet,how to prevent the abnormal microstructure by means of controlling the grain size and microstructure transformation during the accumulating process step by step are the problems to be solved.The microstructure of the nugget zone is lath martensite and bainite,and the microstructure of the heat affected zone is fine martensite.关键词
