This study highlights the weldability of austempered ductile iron (ADI) using laser welding. SEM, EDS and XRD analysis were performed on fusion lines, heat affected zone (HAZ) and melted zone (MZ). Welding speed (Ws) and laser power (P) were varied. The heat affected zone is composed of graphite, perlite and martensite; the melted and solidified zone contains graphite, ferrite and cementite. XRD results are in accordance with SEM micrographs.
