Abstract Scope |
Inconel 718 is an alloy widely used by many industries due to its great performance at high temperatures. Wire arc additive manufacturing (WAAM) can be used to create larger parts with medium to low complexity with a reduced cost and faster manufacturing times than traditional methods. The presence of niobium in this alloy makes it prone to severe segregation during solidification which creates a liquid film and low melting-laves phases that can lead to hot cracking. This work focuses on the effect that process parameters and interpass temperature have on melt pool dimensions and the occurrence of hot cracking in MIG-based WAAM. Understanding this effect allows users to choose the most productive process parameters while maintaining geometric consistency and avoid cracking. |
