Drilling of Cooling Holes by Using High-Power Ultrashort Pulsed Laser Radiation

By Hermann Uchtmann One of the main applications for laser drilling is the manufacturing of cooling holes with diameters of e.g., 500 µm in turbine components such as turbine blades and vanes or combustion chambers. Nowadays, these cooling holes are drilled by using flash lamp pumped Nd:YAG laser radiation and partially by using QCW fiber laser […]

High Deposition Rate Laser Cladding – Recent Advancements

By Jari Tuominen, Jonne Näkki, Henri Pajukoski, Tuomo Peltola, Petri Vuoristo Laser cladding is currently done with 3-6 kW gas and solid state lasers. Components to be clad or repaired are usually small or some discrete regions in larger components. Net deposition rates are typically 1-2 kg/h. In large area coating applications, conventional coating methods […]
