Abstract - Wire arc additive manufacturing (WAAM) is a fusion manufacturing process in which an electric arc's heat energy is employed for melting the electrodes and depositing material layers for wall formation or simultaneously cladding two materials to form a composite structure. This directed energy deposition-arc (DED-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, and low consumption of energy in comparison with the conventional joining processes and other additive manufacturing technologies. 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, molds, and dies industries demonstrates compatibility and reflects comprehensiveness.

By using this process with the help of MIG welding, we are planning to create the 3D object using WAAM technology so that we can check the characteristics as well as mechanical and metallurgical behavior of the 3D object that is created by using MIG welding with the help of WAAM technology
