Wright Dialogue with Industry

July 20-21, 2011
Hope Hotel & Conference Center
Wright-Patterson Air Force Base, Dayton, Ohio

LSP Technologies is proud to attend again this year to discuss it’s laser peening process and services as well as it’s laser bond inspection process.

The following is taken from their website:
The Dayton Area Defense Contractors Association (DaytonDefense) will sponsor the fifth “Wright Dialogue with Industry” conference on July 20-21, 2011 at the Hope Hotel and Conference Center, Wright-Patterson AFB, OH.

The purpose of this conference is to help promote economic development activity among local defense contractors and Wright-Patterson Air Force Base. Please plan to attend this year’s Wright Dialogue with Industry to hear first-hand from key leaders of the Air Force Research Laboratory (AFRL) organization as they discuss both current and future business opportunities.  There will be opportunities throughout the day for more detailed breakout sessions where you can pose your particular questions to the Laboratory representatives. Throughout the course of the event, there will be time to network and discuss opportunities to do business in greater detail with AFRL.

11th International Conference on Shot Peening

South Bend, Indiana

September 12-15, 2011
Booth #111

LSP Technologies happily returns to the the International Conference on Shot Peening in 2011.  David Lahrman and Steve Dykes will be attending the conference and will be available to discuss and explain the laser peening process.  Stop by and visit with them in our booth (#111).  We hope you will stop to learn more about laser peening and how it can improve the fatigue properties of the parts you manufacture or maintain.

The excerpt below from the 11th International Conference on Shot Peening website highlights shot peening alternative or supplemental processes.

“Related mechanical surface treatments, such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes including compressive surface residual stresses, are within the scope of the conference, especially when compared to shot peening.”  To read more, visit the conference website:

The conference is hosted by Electronics, Inc. and The Shot Peener Magazine.  You can also visit the conference host’s websites for more information about them:


11th International Conference on Shot Peening

LSP Technologies will be a presenter.

September 12-15, 2011
South Bend, Indiana

ICSP-11 will be the 11th International Conference on Shot Peening. Related mechanical surface treatments – such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes inducing compressive surface residual stresses – are within the scope of the conference, especially when compared to shot peening. Shot Peening and related mechanical surface treatments have proved to be powerful instruments in enhancing the resistance of components to various kinds of stress-induced damage, particularly with respect to fatigue and corrosion damage. The service lives of a wide variety of structural components, irrespective of shape and dimensions, can be improved dramatically by shot peening. The commercial benefits of applying mechanical surface treatments are increasingly recognized, especially in the automotive and aerospace industries.

2010 Award for Excellence

LSP Technologies, Inc. has been named a co-recipient of the 2010 Award for Excellence in Technology Transfer by the Department of Energy’s Federal Laboratory Consortium (FLC). LSP Technologies was recognized for their contribution toward transferring “Laser Shock Peening for Pilger Dies” to the commercial marketplace in collaboration with Battelle’s Pacific Northwest Laboratory (PNNL) and Sandvik Special Metals (SSM).  LSP Technologies pioneered the commercial development of a metal surface treatment called laser peening in the late 1990s, which was first invented in the 1970s by Battelle researchers in Columbus, Ohio.

Special metalforming tools called pilger dies are used to reduce the circumference and wall thickness of metal tubes. The high operational stresses exerted on the dies during the cold pilgering process can result in frequent die failures, which results in costly downtime.   LSP Technologies, PNNL, and Sandvik teamed to develop and apply laser shock peening techniques to extend steel die life.  Dies treated by LSP Technologies can last up to six times longer than untreated dies. Laser shock peening deters die failures by using high-energy laser pulses to create deep, compressive residual stresses in the die’s surface.  LSP Technologies, Sandvik, and PNNL researchers are studying how the automotive, aerospace, and nuclear industries can benefit from this development.

The DMC is the flagship defense manufacturing technology forum for exchanging ideas, assessing technical project progress and dealing with the challenges of the many new and traditional defense industrial base issues across the services and agencies.

Mobile Laser Bond Inspection System Demonstration

On November 10, 2009 LSP Technologies successfully demonstrated to the USAF the mobile laser bond inspection system that was constructed on two USAF SBIR (small business innovative research) programs.  This advanced pulsed laser inspection system is configured in a self-contained, environmentally-controlled enclosure that sits on a mobile platform.  This advancement is essential for rapid insertion of the LBI process into aircraft manufacturing plant operations and aircraft maintenance depots.  There exists no equivalent laser system in the commercial sector.

Laser Bond Inspection (LBI) is a local proof-testing method that applies a well-controlled dynamic stress to a composite structure, and senses the failure of weak laminate or weak adhesive bonds in response to the stress. The dynamic stress is generated by the interaction of a pulsed laser beam with a composite structure. The controlled stressing of the composite material has no effect on the material or bond if it is not damaged, defective, or substandard. The technique offers a practical structural health monitoring solution for locating composite damage and defect regions in laminate and laminate-adhesive bonds in aircraft.

Benefits of laser bond inspection include the following:

  • Allows the detection of “kissing bonds” in composite structures that are not detectable by standard nondestructive inspection techniques
  • Makes calibrated dynamic strength measurements to find weak areas in composite laminate or adhesive bonds that conventional testing cannot locate
  • LBI may be applied to metal-to-composite and metal-to-metal bonds as well as pure composite assemblies
  • LBI can be applied for inspecting a variety of commercial,  reconnaissance, and targeting aircraft
  • LBI improves reliability and reduce maintenance cost of composite aircraft structures

As program manager of the project, David W Sokol would like to thank Steve Toller, Jim Niehaus, Brad Lance, Rick Mills, and Kevin Romer for all their hard work on the program.  He would also like to thank David Lahrman for working with WPAFB staff in making this USAF SBIR program possible.
