Electronic Weld Record System
Project Participants: Huntington Ingalls – Newport News Shipbuilding Project Start: November 2016 Welding processes at Huntington Ingalls Industries—Newport News Shipbuilding (NNS) require over 25 different forms, including Non Destructive Testing (NDT). All of these forms are manually filled out, and then signed by hand. Information recorded on the forms must be captured and retained to meet internal […]
Non-Contact Metrology In Shipbuilding
Project Participants: Huntington Ingalls Industries – Newport News Shipbuilding Project Start: February 2016 At Huntington Ingalls Industries – Newport News Shipbuilding (HII-NNS) optimization of the shipbuilding process is not only a focus, it is a requirement. If designing, constructing and providing worldwide fleet support for the Virginia Class Submarine (VCS) program was not enough of […]
High Deposition Submerged Arc Welding Ford Class Aircraft Carriers
Project Participants: Newport News Shipbuilding Project Start: June 2015 The U.S. Navy and Newport News Shipbuilding (NNS), a division of Huntington Ingalls Industries, have a joint initiative to reduce the construction cost of FORD-class aircraft carriers (CVN). The Navy ManTech Program is participating in this initiative with specific focus on improving manufacturing processes for ship […]
Synchronizing Material Logistics with CVN Pier & Dry Dock Build Strategies
Project Participants: Newport News Shipbuilding Project Start: August 2014 Newport News Shipbuilding is creating the ability to quickly and easily analyze material impact on build strategy decisions. Naval ship construction is an immensely complex logistical activity involving large quantities of highly specialized material, equipment and personnel. All material that ultimately resides in a CVN must […]
CVN Reality Capture
Project Participants: Newport News Shipbuilding Project Start: November 2013 NNS is executing this 13-month project using an iterative process that will lead to incremental implementations. The NNS team has evaluated current scanning technologies, including those based on laser and infra-red light, capable of capturing 3D shipboard configurations and narrowed the field of shipcheck applicable laser […]
Digital Radiography Transition for Inspection of Welds and Castings
Project Participants: Newport News Shipbuilding Project Start: November 2010 The current film-based radiographic inspection process uses expensive, non-reusable film and chemicals that contain materials (silver) that are potentially hazardous to the environment and wastes thousands of gallons of water every year. This film-based inspection process is also very cycle-time intensive, requiring manual handling of materials […]
Small Weldment Optimized Cell
Project Participants: Northrop Grumman Shipbuilding-Newport News Project Start: August 2007 Small weldments at Northrop Grumman Shipbuilding-Newport News (NGSB-NN) are considered any structural part manufactured or assembled in the small component fabrication and assembly shops (generally up to 4-ft by 8-ft and weighing no more than 5 tons). Current manufacturing and assembly methods for small weldments […]
Digital Radiography- An Alternative to Film Radiography
Project Participants: Northrop Grumman Shipbuilding- Newport News Project Start: November 2004 The current film-based radiographic inspection process uses expensive, non-reusable film and chemicals that contain materials (silver) that are potentially hazardous to the environment and wastes thousands of gallons of water every year. This film-based inspection process is also very cycle-time intensive, requiring manual handling […]
Predictive Weld Distortion in Thick Navy Structures
Project Participants: Northrop Grumman Shipbuilding-Newport News Project Start: November 2004 SShipbuilders often use heat addition (flame straightening) to remove the distortion caused by welding. This labor and time intensive method affects product cost and schedule and is a complicated trial-and-error solution method. Experience can reduce the number of iterations to the solution, but the number […]
High Heat Input Welding of Thick HSLA-100 with Reduced Pre-heat
Project Participants: Northrop Grumman Shipbuilding-Newport News Project Start: August 2004 This Northrop Grumman Shipbuilding – Newport News project was performed to determine the feasibility of joining HSLA-100 with 60°F preheat using high heat inputs with both the mechanized pulsed Gas Metal Arc Welding (GMAW-P) and SAW processes. The project was divided into three phases, the […]
