The laser hot-wire (LHW) process has the potential to deposit material at high rates using low laser power. An LHW experiment was designed to be able to deposit material at the rate of 3.46 kg per hour with less than 10 kW of laser power. Four thermo

Modified 9Cr–1Mo, or P91, is a creep resistance steel grade for high temperature applications. Creep strength and ambient temperature impact toughness are required for welded joints, the latter of which is often a challenge especially for high depo

Laser Hot-Wire (LHW) processing is a subset of freeform welding, which in turn is an extension of the well-established wire-based robotic cladding. The process is adaptable as a viable additive manufacturing (AM) technology. In LHW two separate heat
