| Abstract Scope |
The corrosion resistance and high-strength properties of martensitic stainless steels have led to a focus on development for naval applications. Still, welding and wire-arc additive manufacturing (WAAM) can present unique challenges in processing these materials. A key challenge is determining appropriate processing parameters for WAAM. Finding a process window that can optimize geometry, part quality, and properties requires extensive development time and cost. The described work looks to use an analytical model and physical properties to create an a priori WAAM process window that can predict bead geometries and quality. Predicted qualitative and geometric results are compared to bead-on-plate tests to evaluate model validity. Experimental data for this work were acquired using both an in-situ multi-modal sensor array and an optical profilometer, after which, data analysis provides melt pool and bead geometry information for comparison against the model. |
