High-Pressure Steam Cycle and Boiler Water Treatment

20/11/2012 · This work is devoted to the investigation of the laser–matter interaction during up to 20 kW ytterbium fiber laser welding of thick mild steel plates. The plume attenuation of a probe 1.3 μm wavelength diode laser beam as well as of continuous radiation in the 250–600 nm wavelength range was measured during welding with and without Ar shielding gas supply.

22/2/2019 · The formation of keyholes, or vapor-filled depressions, during laser welding presents a large problem for additive manufacturing. Cunningham et al. used high-speed x-ray imaging to take a detailed look at keyhole formation in a titanium alloy. They found a simplified relationship between operational parameters and keyhole shape, which may allow for the prevention of pore formation going

10/11/2009 · Icicles often grew into the interaction region of the laser during a measurement, despite the extended length of the liquid nitrogen trap (60 cm). The issue was most prominent for droplet streams that were not completely straight and may have impinged the side of the trap, rather than the bottom.
