  • Investigation of laser Consolidation Process for metal powder by two-color pyrometer and high-speed video camera
    CIRP Annals - Manufacturing Technology, 2013
    Co-Authors: Tatsuaki Furumoto, Mohd Rizal Alkahari, Takashi Ueda, Akira Hosokawa
    Abstract:

    This paper deals with the measurement of surface temperature on metal powder during the laser Consolidation Process with two-color pyrometer. Additionally, the aspect of selective laser sintering (SLS) and selective laser melting (SLM) of metal powder is visualized with high speed video camera. As a result, the surface temperature during the laser irradiation was ranged 1520-1810 C and the Consolidation phenomena was classified according to the melting point of metal powder. The metal powder at the heating Process cohered intermittently to the melt pool although the laser beam was continuously irradiated to the powder surface. © 2013 CIRP.

  • Monitoring of Laser Consolidation Process of Metal Powder with High Speed Video Camera
    Physics Procedia, 2012
    Co-Authors: Tatsuaki Furumoto, Mohd Rizal Alkahari, Mohd Sanusi Abdul Aziz, Takashi Ueda, Akira Hosokawa
    Abstract:

    This paper deals with the monitoring of laser Consolidation Process of ferrous based metal powder with high speed video camera. The melting Process and solidifying Process of metallic powder are observed in order to clarify the Consolidation mechanism. The influences of layer thickness of the deposited powder on Consolidation characteristics are investigated. Laser beam used is Yb:fiber laser with a spot diameter of 45 μm and a maximum powder of 40 W. A recording speed of high speed video camera is 10,000 fps. As a result, the aspect of Consolidation Process on powdered surface during laser beam irradiation was visualized.
