Patent number: 11940325Abstract: Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part.Type: GrantFiled: July 21, 2022Date of Patent: March 26, 2024Assignee: The Penn State Research FoundationInventors: Abdalla R.

Patent number: 10046394Abstract: A method for manufacturing material voxel-by-voxel using directed-energy deposition is given. Using the method, unsupported structures, via voxel-wise directed-energy deposition, with steep overhangs is described and demonstrated. Methods for forming arbitrarily-complex structures and shaped voxels and surfaces are also given. A method for forming materials with internally-varying properties is also given. The method utilizes a pulsed or modulated, rather than continuous-wave energy source, thus allowing rapid solidification of voxels, rather than contours, hatches or tracks. Tuning of pulsing or modulation, material flow, and deposition-path parameters allows the buildup of unsupported material using standard directed-energy deposition processing heads and 3-axis stages, for example. The methods are demonstrated using a modified-directed-energy-deposition processes and is applicable to powder-bed for the buildup of three-dimensional components, repair and the addition of features to existing components.Type: GrantFiled: September 14, 2015Date of Patent: August 14, 2018Assignee: The Penn State Research FoundationInventors: Abdalla R.

Patent number: 6236017Abstract: Apparatus for determining a quality of a weld produced by a welding device according to the present invention includes a sensor operatively associated with the welding device. The sensor is responsive to at least one welding process parameter during a welding process and produces a welding process parameter signal that relates to the at least one welding process parameter. A computer connected to the sensor is responsive to the welding process parameter signal produced by the sensor. A user interface operatively associated with the computer allows a user to select a desired welding process. The computer processes the welding process parameter signal produced by the sensor in accordance with one of a constant voltage algorithm, a short duration weld algorithm or a pulsed current analysis module depending on the desired welding process selected by the user. The computer produces output data indicative of the quality of the weld.Type: GrantFiled: July 1, 1999Date of Patent: May 22, 2001Assignee: Bechtel BWXT Idaho, LLCInventors: Herschel B.

Patent number: 5794718Abstract: An impact boring head may comprise a main body having an internal cavity with a front end and a rear end. A striker having a head end and a tail end is slidably mounted in the internal cavity of the main body so that the striker can be reciprocated between a forward position and an aft position in response to hydraulic pressure. A compressible gas contained in the internal cavity between the head end of the striker and the front end of the internal cavity returns the striker to the aft position upon removal of the hydraulic pressure.Type: GrantFiled: March 11, 1996Date of Patent: August 18, 1998Assignee: Lockheed Idaho Technologies CompanyInventors: W.
