Wire arc-based additive manufacturing (WAAM) process is one of the promising manufacturing methods for the manufacturing of large and complex metallic component. GTAW-based deposition results in higher quality with almost no splash and it creates less pollution; hence, it is highly suitable for application in producing the more accurate components. The selection and optimization of WAAM process parameter is very critical to achieve the satisfactory geometrical and dimension dimensional accuracy of fabricated products. Consequently, present work uses the GTAW-based WAAM for deposition of Ti6Al4V wire on Ti6Al4V substrate. The WAAM of Ti6AL4V has been carried out at three levels of wire feed varying from 0.6 to 1.8 m/min at an interval of 0.6 m/min and at the two levels of current of 80 and 100 A. The torch travel speed has been kept constant at 50 mm/min. The analysis of bead formed at different parameters shows that minimum width of bead can be produced at lower feed of 0.6 m/min and at higher current of 100 A. However, higher height of bead has been produced at higher feed of 1.2 m/min and at lower current of 80 A. Optical parameters analysis of the images of bead along the deposited length has been found to be capturing the variation in surface topography of bead produced at different WAAM process conditions. The proposed CNN architecture has been found to be classifying the defect and defect-free deposition with good accuracy.
