“…Similar research works can also be found in high temperature process, such as Pulsed Gas Metal Arc Welding (P-GMAW) where a centimeter metal liquid pool is supplied by a millimeter liquid metal droplet (Fig. 1) [8]. It was shown that the gas-liquid-solid line motion was modified with different process parameters and shielding gas.…”

“…One point is assimilated to a spherical cap with a radius R deposit . Previous studies have shown the complex relationship that can exist between process parameters and the geometry of the spherical cap [8]. The radius R deposit depends on the quantity of mass and the base radius of the spherical cap.…”

Wire Arc Addtive Manufacturing (WAAM) is a promising direct energy deposition technology to produce high-value material components with a low buy-to-fly ratio. WAAM is able to produce thin-walled structures of large scale and also truss structures without any support. To manufacture complex parts, process reliability and repeatability are still a necessity and this often leads to long developing times. In this paper, a method is proposed to automatically manufacture complex truss structures with point by point arc additive manufacturing and a six axis robot. Computer aided manufacturing (CAM) software is designed to manage (i) material deposition at intersections and (ii) collisions between the part under construction and the torch. Because it is difficult to model the deposition process, the bead geometry is monitored using video imaging. Image treatment program detects the contour of the deposit and computes its current position. With this position, the CAM software corrects the geometry of the part for future deposition. Simple case studies are tested to validate the algorithm. Two solid free form geometries designed by topology optimization are manufactured with this skeleton arc additive manufacturing process.
