Wire Arc Additive Manufacturing (WAAM) is an updated version of Gas Metal Arc Welding (GMAW) process that is used to fabricate three-dimensional parts by melting and depositing material in a layer-by-layer manner. In this study, an attempt has been made to fabricate a thick wall through WAAM process using optimum inter-track or inter-pass offset to achieve dimensional accuracy of the fabricated part. Additionally, surface texture analysis has been performed for the experimental validation of the theoretical model of optimum inter-track offset. The experimental validation confirms that the use of optimum inter-track offset produces smooth and flat surfaces through a reduction in surface roughness and waviness. The average roughness at the overlapped region of two adjacent beads is found to be 1.14 microns. The improvement in surface quality is accounted for selecting the value of inter-track offset equal to two-thirds of bead width.

摘要

Wire Arc Additive Manufacturing (WAAM) is an updated version of Gas Metal Arc Welding (GMAW) process that is used to fabricate three-dimensional parts by melting and depositing material in a layer-by-layer manner. In this study, an attempt has been made to fabricate a thick wall through WAAM process using optimum inter-track or inter-pass offset to achieve dimensional accuracy of the fabricated part. Additionally, surface texture analysis has been performed for the experimental validation of the theoretical model of optimum inter-track offset. The experimental validation confirms that the use of optimum inter-track offset produces smooth and flat surfaces through a reduction in surface roughness and waviness. The average roughness at the overlapped region of two adjacent beads is found to be 1.14 microns. The improvement in surface quality is accounted for selecting the value of inter-track offset equal to two-thirds of bead width.
