    Zoom Vision System For Robotic Welding (1990)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Rugged zoom lens subsystem proposed for use in along-the-torch vision system of robotic welder. Enables system to adapt, via simple mechanical adjustments, to gas cups of different lengths, electrodes of different protrusions, and/or different distances between end of electrode and workpiece. Unnecessary to change optical components to accommodate changes in geometry. Easy to calibrate with respect to object in view. Provides variable focus and variable magnification.

    Conservative Overset Grids for Overflow For The Sonic Wave Atmospheric Propagation Project (1999)
    In:  CASI
    Details
    Publication Date: 2019-07-10
    Description: Methods are presented that can be used to make multiple, overset grids communicate in a conservative manner. The methods are developed for use with the Chimera overset method using the PEGSUS code and the OVERFLOW solver.

    Infrared Thermography For Welding (1992)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Infrared imaging and image-data-processing system shows temperatures of joint during welding and provides data from which rates of heating and cooling determined. Information used to control welding parameters to ensure reliable joints, in materials which microstructures and associated metallurgical and mechanical properties depend strongly on rates of heating and cooling. Applicable to variety of processes, including tungsten/inert-gas welding; plasma, laser, and resistance welding; cutting; and brazing.
