Joining Technologies to Showcase Laser Additive Manufacturing at AeroDef

Joining Technologies, an innovator in laser cladding, electron beam and laser welding applications, announces that it will showcase its laser additive manufacturing capabilities at the Society of Manufacturing Engineers’ AeroDef Manufacturing Exposition and Conference, to be held Apr. 5-7, 2011 at the Anaheim Convention Center in Anaheim, CA.

Joining Technologies has launched a new laser additive manufacturing division, and entered into a formal Cooperation Agreement with world-renowned laser development and contract research institute Fraunhofer Institute for Laser Technology (ILT). The resulting partnership,Joining Technologies Research Center (JTRC), will be showcased at AeroDef.

Fraunhofer ILT’s Dr. Ingo Kelbassa will give a presentation entitled, “Additive BLISK Manufacture,” discussing the qualification and certification of laser metal deposition (LMD) for the green manufacture of new and future generation parts such as BLISKs (BLade Integrated DiSKs) made from Nickel and Titanium base alloys. The presentation discusses the method from feasibility studies, through process development, to a first additive BLISK-mock-up manufacture for an HPC BLISK made from Inconel 718.

As part of JTRC, Fraunhofer ILT will be providing laser additive manufacturing research and development services, as well as system design and integration and accessory sales, including nozzles and cladding heads, all from its new facility in East Granby, CT. The JTRC partnership will offer a range of services, from feasibility studies via process development, validation and certification, to systems engineering and system integration of a customized industrial solution at a customer’s site.

“Our new partnership with Fraunhofer ILT combines the precision and reliability of Joining Technologies’ laser cladding processes with ILT’s cutting edge laser additive research and development capabilities,” said Scott Poeppel, Joining Technologies’ manager of additive processes. “The JTRC partnership offers customers enhanced information on using laser additive manufacturing for repair or restoration in aerospace, power generation, valve, and OEM-supplied component applications.”

Dr. Ingo Kelbassa, vice and academic director of LLT, RWTH Aachen University and head of the RWTH LLT department at Fraunhofer ILT, expects the JTRC partnership will offer a range of services from feasibility studies through final industrial implementation. “By using such process-specific advantages as nearly unrestricted geometrical freedom, material freedom and achievable thermo-mechanical properties of the parts built-up, it is possible to manufacture parts designed specifically for their function,” said Dr. Kelbassa. “Laser additive manufacturing can therefore be considered as the key enabler for the green manufacturing of new and future generation parts.”

Dr. Kelbassa is also the responsible representative of LLT, RWTH Aachen University for basic and fundamental cooperative R&D initiatives in China as well as Fraunhofer ILT’s representative for cooperative applied science projects in North America and Australia.

Fraunhofer Institute for Laser Technology is an internationally known laser development and contract research institute with more than 250 employees and 10,000m² of usable floor space, fitted out with the latest technical and scientific infrastructure and equipment. It focuses on the development of new laser beam sources and components, the use of modern laser measurement and testing technology, and laser-supported manufacturing. It is also working in the area of laser plant technology and process control.

AeroDef Manufacturing is an event that provides manufacturing solutions for the unique needs of aerospace and defense manufacturers. The even aims to find new sources of innovation that can drive efficiencies throughout the manufacturing process and maintain U.S. defense and commercial superiority.
