| Abstract Scope |
Electroslag strip cladding (ESC) is a high-productivity welding process that has significantly higher deposition rates than gas metal arc welding (GMAW) directed energy deposition (DED) additive manufacturing (AM). The granulated flux, large slag puddle, and large melt pool associated with ESC complicates extension of the process to electroslag AM (ESAM). We document the design of a multi-process ESAM system that combines GMAW DED with ESC. Parallel beads with engineered gaps are printed using GMAW DED. Subsequently, the gaps between parallel GMAW beads serve as a trough to contain the flux, slag, and melt pool of ESC. We characterize the GMAW and ESC interface for metallurgical bonding. Further, we also characterize the material properties in the ESC and GMAW regions. Comparisons are given between ESAM and other additive and conventional manufacturing routes. |
