Abstract

Wire Arc Additive Manufacturing (WAAM) is the process of using Arc Welding to design and create metal parts. This is one of many additive manufacturing (AM) processes used in commercial and private use. WAAM manufactures parts by printing layers of weld beads on top of one another. Printing in this way can be done using conventional stringer bead welding, which is printing in a straight line along the print path, or by moving the print head in a non-linear pattern, known as weaving, along the print path. This research examines the changes in properties of specimens printed using stringer walls and weave pattern walls, mostly examining the porosity and microstructure of the specimens. This research serves to provide information regarding better printing practices among those who employ WAAM in production, leading to stronger and safer products.
