The present work investigated the effects of a submerged arc welding process with high weaving amplitudes (up to 40 mm) on the weld beads morphological aspects. For this purpose, bead-on-plate welding tests with different welding energies and weaving parameters were performed. As a result, weld beads of up to 45 mm width, free of discontinuities, and with at penetration pro les were obtained.Based on this, we have a single wire process able to ll grooves more e ciently and, at the same time, working for cladding applications.
