LSPT Demonstrating Laser Peen Forming for American Shipbuilders

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

Model and sample of laser peen formed dual curvatureLaser 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

Fiery Engine Failure Caused by Metal Fatigue

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.

A Valentine’s Day Poem About Metal Fatigue :)

Total Fatigue of the Heart

Roses are red,
Violets are blue,
Metal fatigue
Broke my heart into two.

Millions of cycles,
Decades of strain,
Fatigue cracks and failure
Are really a pain.

FOD and corrosion,
Fretting and creep,
I need a solution
That penetrates deep.

Shot peening failed me,
Burnishing too,
Such shallow compression
Just simply won’t do.

Silhouette of Cupid firing a red laser to trace a red heart

But then – inspiration,
A pulse to the chest,
A better approach
To residual stress. Continue reading

LSP Technologies, Inc. Delivers Diode-Pumped YAG Laser System for Laser Glass Damage Testing

Laser processing services and equipment provider LSP Technologies delivers a custom laser system to SCHOTT North America.

Laser Glass Damage Testing System - Red and black enclosure in manufacturing facilityDublin, 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.”

Air Force Research Laboratory Touts Laser Bond Inspection

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.

Air Force Collaboration Could Increase Use of Composites in Aerospace Manufacturing

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.
