New Paper – Pulsed Gas Metal Arc Welding of Copper-nickel Pipe Joints

CaptureCopper-nickel alloys are often used in shipbuilding for applications such as tanks, seawater and freshwater piping, and numerous other structures. Copper-nickel pipe joints are typically welded with manual gas tungsten arc welding; however, inherently slow travel speeds and low deposition rates impede productivity. The implementation of pulsed gas metal arc welding (GMAW-P) could yield significant productivity benefits for semi-automatic, mechanized, or robotic applications through the use of faster travel speeds and increased deposition rates.

Under funding from the National Shipbuilding Research Program Advanced Shipbuilding Enterprise, EWI worked with two shipyards to explore the benefits of modern digitally controlled GMAW-P power sources and develop procedures that meet NAVSEA qualification requirements for these joints. EWI Applications Engineer Nick Kapustka and Business Development Manager for Government Programs Paul Blomquist have written Pulsed Gas Metal Arc Welding of Copper-nickel Pipe Joints to discuss this collaboration.

3D Vision-guided Robotics for Industrial Applications — New Paper

Advanced robot-based object detection, recognition, and gripping technologies have seen increasing use as manufacturers transition from mass production to customization to meet customer demands. As a result, today’s modern robotic systems must be able to recognize a changing environment and adapt to it.Capture1.PNG

Advanced vision techniques ranging from low-resolution systems with a large field of view, to high-precision surface metrology systems are available to solve a wide range of challenging industrial applications.

3D vision point cloud dataEWI Applications Engineer Seungkook Jun has written 3D Vision-guided Robotics for Industrial Applications to provide an overview of advanced vision techniques ranging from low-resolution systems with a large field of view to high-precision surface metrology systems. This paper describes four different 3D imaging techniques, and provides examples of their application in industry.

New Guide: NDE Breakthroughs that Ensure System Integrity and Lifetime Quality

thumbnail_NDE_QUALITY_TESTING_10172Advanced nondestructive evaluation (NDE) allow manufacturers to more effectively comply with standards and regulations, extend the life of equipment, vehicles, and infrastructure, and reduce the risk of service failures. Now, new developments are enabling companies to implement NDE earlier in the manufacturing timeline— gaining value for not just in-service assets, but during new product development and manufacturing to ensure first-time and lifetime quality.

EWI’s new eguide, Nondestructive Evaluation: Using Breakthrough Technology to Ensure First-Time Quality, explores the many advantages of NDE across the product lifecycle. The eguide features:

  • New developments in NDE
  • Benefits of NDE from concept to service
  • EWI’s state-of-the-art NDE capabilities
  • And more

South Korean Delegation Visits EWI, Signs Collaboration Agreement

Representatives from Ulsan Metropolitan City and EWI sign a memorandum of understanding

Representatives from Ulsan Metropolitan City and EWI sign a memorandum of understanding

On Wednesday, June 7, EWI hosted a contingent from the Ulsan Metropolitan City, Republic of Korea, to sign a collaboration agreement to pursue R&D activities for the mutual benefit of both parties. These include a project funded by the South Korean government to develop next-generation additive manufacturing (AM) technologies, a staff exchange to foster collaborative research and development in manufacturing innovation, and the exploration of establishing an EWI-operated research center in Ulsan to serve South Korea and the greater Asia Pacific Region.

The delegation from South Korea’s “capital city of industries,” led by Ulsan Governor Kim Gi-hyeon, met with EWI executives and technology leaders at the company’s Ohio headquarters to officially formalize their collaborative relationship in a brief signing ceremony. The visitors later had the opportunity to tour the Columbus laboratories to see the range of innovative technologies and manufacturing solutions being developed by EWI to advance manufacturing in a competitive global market.

“We are honored that you have made this visit to our flagship facility,” said EWI President and CEO Henry Cialone to the Ulsan guests. “We are very excited about the prospects for collaboration under our new MOU [Memorandum of Understanding], including the possibility of establishing EWI Korea in Ulsan.

Following the visit to EWI in Columbus, several members of the Ulsan delegation traveled on to Buffalo Manufacturing Works in western New York, where they toured another one of EWI’s state-of-the-art research labs.

Collaborative activities between EWI and Ulsan will begin in the coming months.

Just Published: Computer-Aided Programming for Robotic Welding

Congratulations to EWI Senior Project Manager Harvey Castner and his colleague Jeff Penoyer at Wolf Robotics for their published article in June 2017 issue of Welding Journal.

Their article, “Computer-Aided Programming for Robotic Welding,” explores how new technologies eliminate automation cost barriers and enable automated robot programming, benefitting low-volume industries such as shipbuilding.  Specifically, the article addresses the NSRP-ASE -sponsored project CAR-W which was awarded in April 2015 .  The project aims to develop technologies that enable rapid automated programming of robotic welding systems for highly-varied and complex structures.

EWI Research on Ultrasonic-Assisted Drilling published in International Journal of Advanced Manufacturing Technology

Image 3 AminA new article co-authored by EWI associates Amin Moghaddas, Matt Short, Nick Wiley, and Karl Graff, along with Allen Yi of The Ohio State University, was recently published in The International Journal of Advanced Manufacturing Technology.

The article titled “Performance of an Ultrasonic-Assisted Drilling Module” discusses how the ultrasonic-assisted drilling module, designed using FEA methods with a 16 mm carbide drill, is used to study the effects of ultrasonics on thrust force, torque, surface quality, hole size, and the microstructure of drilled 4340 steel. Also, discover how ultrasonics vibrations not only can reduce the average values of thrust force and torque but also can improve the surface quality of the hole.Image1 AminImage2 Amin
