Application Of Tig-Mig Hybrid For Wire Arc Additive Manufacturing (Waam)

Wire arc additive manufacturing (WAAM) is an advanced fabrication technology in three-dimensional (3D) printing that deposited metal material layer-by-layer using electric arc as a heat source to form the final part. However, the excessive heat input was the major challenge of manufacturing WAAM wil...
