Research progress on welding performance of additive manufacturing metallic materials
As an innovative manufacturing technology,additive manufacturing(AM)has received widespread atten-tion and application in the field of metallic materials in recent years.However,in practical engineering applications,metallic materials produced by AM often require welding to achieve the assembly and repair of complex structures.Therefore,studying the welding performance of metallic materials produced by AM is of great significance.This pa-per reviews the recent research progresses on the welding performance of metallic materials produced by AM,in-cluding titanium alloys,stainless steel,aluminum alloys prepared by different AM methods,and the study on the mi-crostructure and mechanical properties of welded joints of other metals.Through a systematic summary of the above contents,this paper reveals the main influencing factors and mechanisms affecting the welding performance of me-tallic materials produced by AM,and points out the challenges in current research and future research directions.
