LSP Technologies is set to host a major event highlighting development work with the National Shipbuilding Research Program.
This Thursday, February 22nd, LSP Technologies will host guests from around the country to demonstrate Laser Peening applications for the maritime industry. The event, “Foundational Technology for Scanning and Laser Peening in Shipyards” highlights LSPT’s work with the National Shipbuilding Research Program (NSRP), developing Laser Peening applications for naval vessel construction and sustainment.
Laser Peening is a powerful metal improvement method for component life extension. The process uses high-energy laser pulses to generate deep compressive residual stresses which inhibit cracking and prevent failures. The aerospace industry employs Laser Peening to protect high-value aircraft components, and now the maritime industry is exploring Laser Peening applications to facilitate shipbuilding and repair.
Laser Peen Forming
Laser Peen Forming harnesses the power of controlled plastic strain to form and shape metal components. The process generates deep compressive residual stresses which can be tailored to correct distortions or produce specific curvatures in a part.
Two main benefits of Laser Peen Forming:
Laser Peening produces stress distributions that can be modeled using analytical tools. This allows engineers to simulate Laser Peening process effects and design applications that produce desired curvatures or shapes.
Laser Peening improves metal fatigue strength and damage tolerance, protecting components from fatigue cracking, corrosion, and premature failure.
With the aid of 3D scanning and modeling techniques, Laser Peening can shape metal parts to precise geometric configurations while improving the material’s resistance to cracking and corrosion. Continue reading →
The National Transportation Safety Board (NTSB) released its report on a fiery engine failure that occurred at Chicago O’Hare International Airport in October, 2016. A high-pressure turbine disc ruptured as American Airlines Flight 383 accelerated down the runway, launching heavy fragments and debris up to half a mile away. Pilots aborted the takeoff and 170 people evacuated the aircraft as fire consumed the right engine and wing.
Laser processing services and equipment provider LSP Technologies delivers a custom laser system to SCHOTT North America.
Dublin, Ohio, February 6, 2018 – LSP Technologies, Inc. (LSPT) has built and delivered a state-of-the-art Laser Glass Damage Testing (LGDT) system to SCHOTT North America, Inc. in Duryea, PA. SCHOTT will use this system to inspect their phosphate laser glass for platinum inclusions.
A leading manufacturer of laser and optical glass, SCHOTT required a new glass inspection system late in 2015. SCHOTT contracted with LSPT who provided contract inspection services while LSPT built them a new integrated inspection system.
“We are excited that SCHOTT chose to rely upon LSPT’s experience with high-energy laser systems to supply their new inspection laser,” said David Lahrman, Vice President of Business Development for LSP Technologies, Inc. “Our successful delivery of this cutting-edge system further enhances the 21-year relationship between SCHOTT and LSPT, and we look forward to a continued partnership with them, now both as a customer and a supplier.”
Laser Bond Inspection (LBI) is a nondestructive inspection method for evaluating bonded composite structures. The U.S. Air Force and The Boeing Company are currently using LBI to develop composite airframe designs and manufacturing processes. The Air Force Research Laboratory, located at Wright-Patterson Air Force Base in southwest Ohio, recently published an article highlighting the capabilities of LBI, and the industry impact of reliable composite manufacturing.
A highlight from the piece:
LBI is the only reliable and mature method capable of assessing the integrity of adhesive bonds in composite structures and detecting kissing bonds, a bond line defect where two surfaces are in intimate contact but are not properly bonded.

Bonded composite airframe structures offer a potential to achieve more affordable manufacturing and more efficient structures, ultimately meeting the goals of the Air Force for increased range and reduced fuel consumption.
Laser Bond Inspection (LBI) in conjunction with bond process control is an enabling technology to transition primary bonded composite structures and realize these goals.
Composite structures, when joined using adhesive bonding rather than traditional rivets or fasteners, require a new inspection process to verify the strength and safety of the composite bonds.
LBI is a stress test to ensure that adhesively fastened structures are joined correctly using a bond’s response to a high-energy pulsed laser generated stress wave to detect structurally substandard bonds.
Laser shock peening (LSP) has revolutionized surface enhancement, achieving new benchmarks in metal fatigue resistance and failure prevention. The laser peening process uses high-energy pulses to produce powerful shockwaves on the surface of metal components. These mechanical shockwaves plastically deform the material, producing compressive residual stresses that reach depths previously unachievable with peening and rolling technologies.
As laser peening gained adoption with gas and steam turbine manufacturers, aerospace and power generation customers have saved millions of dollars by achieving longer service lifetimes, reduced component failures, decreased inspection requirements and reduced maintenance costs. These performance benefits validate laser peening as a cost-saving industrial application to prevent part failure caused by fatigue cracking, stress corrosion cracking, or foreign object damage.

Brian Brown has been with LSP Technologies since 2005, overseeing the organization’s AS9100/ISO9001 Quality Management System.
What attracted you to a career in quality management with LSP Technologies?
I studied Ceramics Engineering at The Ohio State University, and I was ultimately drawn to process engineering as it relates to materials science. I enjoy optimizing LSPT’s production operations, and making sure our innovative solutions conform with customer requirements and industry standards.
In my time as Quality Manager at LSPT, I’ve gotten to work within all levels of our organization. I work alongside executives, engineers, project managers and production workers. I’m able to connect high-level business plans with on-the-floor operations, and contribute directly to our customers’ success. I think my favorite aspect of quality management is the connectedness of the role. It gives me a sense of purpose that I can wrap my mind around at the end of the day.
What are LSPT’s top-level quality objectives, and how do they inform decision-making?
