The Laser Hot Wire process is a wire-based metal deposition and joining process that has commercial applications in overlay, welding, and freeform fabrication. The dual heat source, laser beam and resistively heated wire, enables high deposition rates and flexible and robust control in shape and metallurgy of metal deposits. This process has been used to deposit freeform parts using Ti-6Al-4V wire as feedstock using different strategies for local and global shielding and correlate it to mechanical performance and microstructure. The effect of nitrogen and oxygen contamination on defect formation is characterized.
