LSP Technologies will host a free webinar on Laser Peen Forming technology and applications on Wednesday, June 26, at 11 a.m. EDT.  Click here to register for the webinar today.

Stan Bovid

Stan Bovid, LSPT Director of Materials Research will share details on laser peen forming benefits, including
• Case study – aluminum hull repair for the maritime industry
• Case study – straightening engine crank shafts for life improvement and distortion correction
• Finite element modeling to apply laser peening for precisely shaped parts
• Effective laser peen forming for an increasingly wide range of metals

Laser peen forming maximizes the material benefits of LSP, while attuning the inherent relationship between stress and strain within the metal to create complex, stable shapes.

Because these distributions are readily responsive to today’s analytical modeling tools, we can use Finite Element Analysis (FEA) to simulate the imparted plastic strain along with the elastic response of the surrounding material. This allows accurate, scalable predictions that translate into a vast array of unique curvatures and shapes.

Our speaker, Stan Bovid, is a Ph.D. candidate in materials science at The Ohio State University. He is an expert in metallurgy and computer modeling of industrial metals for aerospace, automotive, heavy equipment, medical, and power generation applications. At LSPT, Bovid manages application development engineering for customers and the company’s materials science testing laboratory and center of excellence.

Jeff Dulaney founded LSP Technologies in 1995

LSP Technologies President and CEO Jeff Dulaney, center, became a regional finalist for the EY Entrepreneur of the Year (EOY) Award.  “This is a great honor not only for me, but also for the 59 team members of LSP Technologies,” Dr. Dulaney said. “Together, we are working every day to build a hungry, humble, and smart culture. The way we work together is just as important as our leadership in laser peening technology.”

LSP Technologies recently moved to a new headquarters in Dublin, Ohio, that more than tripled its footprint. The engineering staff has tripled, and sales to aerospace, power generation, and manufacturing customers are accelerating.

“We adopted a new business model with an emphasis on rapid innovation to proliferate our laser peening technology. To do that, we make laser peening equipment, including custom solutions, that puts our valuable processes into the customer’s own manufacturing and maintenance processes,” Dr. Dulaney said.

“We recruited new engineers and technicians, and then we challenged them with some of the most formidable problems — hazardous environments, huge immovable parts, hard-to-reach surfaces, and complex geometries. Every day these new team members join with our veterans to find new solutions for customers,” he added.

“That combination of sophisticated laser technology, smart innovation, and a humble, hungry, and smart business culture have worked together to unlock the growth potential of LSP Technologies,” he said.

Ask Greg about Laser Bond Inspection for adhesive bonding of composite materials

Greg Karst, Product Line Manager for LSP Technologies, Inc.’s composites business, is attending SAMPE 2019 May 20-23 in Charlotte, North Carolina. SAMPE 2019 attracts more than 3,000 materials and process engineers, as well as exhibits of more than 250 suppliers, manufacturers and service providers.

This is the 75th anniversary of the Society for the Advancement of Material and Process Engineering (SAMPE®), a global professional member society that provides enhanced educational opportunities by delivering information on new and advanced materials and processing technology. For more information, see https://www.sampeamerica.org.

Karst manages and promotes commercial business opportunities for the Laser Bond Inspection (LBI) technologies patented by LSP Technologies. LBI is a non-destructive testing method for assessing the integrity of adhesively bonded composite materials.

The LBI method is based upon stresswave dynamics in bonded materials. LBI uses a pulsed laser system to generate a compressive stress wave on the material surface. The stresswave propagates through the material, and is reflected off the back free surface as a tensile wave. The reflected tensile wave passes through the bondline and stresses the adhesive bond at a selected strength value.

Laser Bond Inspection power levels pinpoint adhesive bond integrity levels

LSP Technologies’ David Sokol explains non-destructive LBI process

In a recent webinar, LSP Technologies Director of Research David Sokol explains how the company’s non-destructive Laser Bond Inspection (LBI) technology can detect faulty bonds, including kissing bonds where the materials are in contact with each other but have no structural integrity.

Adhesive seals for composite materials pose a subtle challenge for quality control and safety, and that is how to detect problematic adhesive bonding without damaging materials or the adhesive bond itself.

A key step in the LBI process is to gradually increase the fluence, or power density, measured as Joules per square centimeter, for laser beams used to measure the integrity of composite adhesive bonds.

LBI readings show shock wave shapes that either reveal integrity in composite adhesive bonds or indicate clear failure in the bonds.  The LBI process, at controlled levels, do not damage materials or compromise the integrity of healthily bonded composites.

 

 

 


Laser Peening to Enhance Additive Manufacturing

Laser peening to treat cracks and voids in additive manufacturing

Laser peening might be one of the key next steps for additive manufacturing.

3-D printing, or additive manufacturing (AM), started as a popular modeling and prototyping tool. Today, Airbus has more than 1,000 3-D printed parts on its A-350 XWB jets, while Lockheed Martin and Boeing are aggressively incorporating the technology as well.

“From simple geometry parts with lots of cracks and voids that you risk breaking in your hand, they’ve come a long way toward robust parts that are actually being used in different industries,” said Micheal Kattoura, a Materials Sciences Engineer at LSP Technologies.

Mission-Critical AM Components

Can AM parts serve in mission-critical functions, facing high pressures, cracking and corrosion? Right now, that depends on the development of strategies for strengthening AM-manufactured parts to compensate for their weaknesses.

Kattoura worked on AM parts and laser peening during his postgraduate work at the University of Cincinnati, and he recently explored the potential of laser peening for improving metal alloys at the 2019 TMS Annual Meeting & Exhibition in San Antonio, Texas, one of the largest annual material science conferences with 4,000 attendees.

The conference featured a symposium on Additive Manufacturing of Metals, or 3-D printing using powdered metals. Kattoura presented his own academic research, entitled, “Effect of Laser Shock Peening Processing Parameters on the Microstructure, Residual Stress, and Fatigue Behavior of Additive Manufactured CoCr Alloy.”

Laser peening has a great deal of promise for enhancing the performance of parts created in additive manufacturing (AM), Kattoura concluded. Manufacturers should soon explore laser peening to provide parts with higher performance and safety, he believes.
