A review on wire arc additive manufacturing based on cold metal transfer
Rajendra Prasad Meena,N. Yuvaraj,. Vipin +2 more
TL;DR: WAAM is a popular additive manufacturing technique for fabricating large metal structures using CMT process. It produces clean surfaces and little spatter. The mechanical properties and microstructure of WAAM-fabricated metals and alloys are comparable to cast or wrought material. However, high residual stresses, porosity, delamination, and fracture are common difficulties encountered in WAAM. Defect-reduction strategies and advancements are discussed.
