Abstract
Wire arc additive manufacturing (WAAM) is a fusion manufacturing process in which the heat energy of an electric arc is employed for melting the electrodes and depositing material layers for wall formation or for simultaneously cladding two materials in order to form a composite structure. Wire and arc additive manufacturing (WAAM) process is a group of additive manufacturing (AM) techniques that use an electric arc as a heat source and a metal wire as a feedstock for the fabrication of 3D metallic components in a layer-based manufacturing process. This directed energy deposition-arc method is advantageous and efficient as it produces large parts with structural integrity due to the high deposition rates, reduced wastage of raw material. These features have resulted in a constant and continuous increase in interest in this modern manufacturing technique which demands further studies to promote new industrial applications. The high demand for WAAM in aerospace, automobile, nuclear, and dies industries demonstrates compatibility and reflects comprehensiveness.
