How LSP Technologies controls lasers to shape metal alloys
Stan Bovid, LSPT Director of Materials Research hosted a webinar on laser peen forming on June 26, 2019. Laser peen forming can produce a unique curvatures and metal shapes, and finite element analysis modeling can predict the precise power levels and peening patterns to transform metal alloys.
The technology can be applied to aviation, maritime (including repairs), and other industries where precise metal shaping is required. In this excerpt of the webinar, Bovid explains how LSP Technologies models different modes of laser peen forming and uses a variety of laser peening parameters to achieve the desired shape.
Features laser peen forming case studies in maritime and automotive industries
Imagine the ability to shape metal parts to precise geometric curves and configurations. That’s the power of Laser Peen Forming, the process of focusing high-powered laser peening to form and shape components.
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, 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.

Laser Peening already prevents damage to metal components, leading to lighter, less expensive, high performance parts
Laser peening can counteract metal fatigue, cracking, corrosion, fretting, erosion, cavitation, and other surface damages. Not only does laser peening prevent costly failures, but it also extends component lifetimes. The long-term benefits of laser peening will be even more dramatic in the future.
With added metal fatigue strength, engineers and designers can opt for lighter and less expensive parts, increasing the return on investment for the technology. This brings a secondary advantage to laser peening.
Why add cost to a part? Instead of relying on more expensive alloys or complicated designs, laser peening can increase your return while providing you with much more flexibility and an improvement in performance. “We are improving the fatigue life of these parts by 2, 5, to 10 times – meaning rather than using 2, 5, to 10 parts – you are only using 1. That’s when you start understanding how much the cost of applying this process is minor compared to the savings you are receiving,” Dr. Micheal Kattoura, highlights.
That’s a key message of the March 2019 webinar presentation by Dr. Kattoura, a materials scientist with LSP Technologies, in this short excerpt from his webinar presentation. To view the PowerPoint presentation, please download the file below the video.

The March webinar in our 2019 series is “The Laser Peening Prescription,” an overview of what laser peening is, how LSP Technologies delivers laser peening, and the benefits for metal components.
From LSP Technologies, you’ll hear from Stan Bovid, Director of Materials Research, and Micheal Kattoura, Materials Scientist, discussing a range of laser peening strategies for improving the fatigue life of metal components.
Here’s an excerpt from the February 2019 LSP Technologies webinar
In 2018, LSP Technologies introduced the world’s first commercially available laser peening system. In 2019, customers are driving even more dramatic innovations.
In this excerpt from the February 6, 2019 webinar, Chief Operating Officer Eric Collet describes a transformational challenge to LSP Technologies: Moving the laser beam delivery system itself to meet customer needs.
Traditionally, LSP Technologies has delivered laser peening with a fixed beam onto parts moving with precision while attached to robotic arms.
The Procudo® Laser Peening System was a revolution in itself, the only commercially available laser peening system, ideal for manufacturing, metal surface job shops and maintenance operations.
But then customers realized the potential. “Ultimately we’re responding to increased customer demand to be able to process larger parts and get into more complicated geometries. As we listen to the customers, we’re really looking to build, in addition to the Procudo® Laser Peening System, some specialized laser peening solutions that are flexible, portable and reliable.”
“We’re really stretching ourselves, freeing ourselves from that restriction of moving the part in front of the fixed beam, and actually taking the laser peening process to the part through being able to manipulate the beam delivery system. In some cases we’re leveraging the Procudo® Laser Peening System as the laser source. In some cases the laser peening solution is completely different.”
The dramatic change is laser beam delivery has led to a vastly expanded LSP Technologies team in mechanical engineering, optical technology, design, and automation. Laser peening will be delivered via fiber optics, special articulated arms, and other systems.
