Exploring a novel panel-core connection method of large size lattice sandwich structure based on wire arc additive manufacturing

Large size sandwich structure is involved in a wide range of applications, such as aerospace and ship. However, the weak connection between panel and lattice is the bottleneck problem restricting their application. To solve this problem, this work demonstrates a novel circular scanning connection me...
