June 26 webinar on laser peen forming

 

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

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 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.

Customizing Laser Peening for Your Parts

Here’s how we work with you and your metal components

Every manufactured metal component is different, performing its functions under widely varying operating conditions. At LSP Technologies, we study the precise nature of threats to metal integrity. Then we design a program of laser peening with tightly designed parameters. The result: improved component reliability, endurance, and safety.

We’ve recently added two pages to the website to help customers know what to expect as we develop customized solutions for parts:

  • Precise Laser Peening Parameters Protect Your Metal Parts
    The goal of laser peening is to produce deep residual compressive stresses from the surface of metals. To achieve the desired stress, we manipulate the laser beam’s energy level, spot size, and pulse width. We can also change the angle of attack on the beam, how frequently we deliver laser peening pulses, and how many layers of spots we apply to the part.

  • The LSP Technologies Application Development Process
    We simplify the laser peening solutions process so customers know exactly what to expect. We walk through the steps from initial discussions about your parts through quote, modeling, and solution design. We’ll test to verify results. Ultimately, we’ll find the laser peening services or laser peening equipment solution that fits. We believe the LSP Technologies difference is our experience, engineering, flexibility, and focus on customer satisfaction.

Laser peening prevents and arrests cracking, corrosion, and other types of metal failure. The deeper these stresses penetrate through laser peening, the better we can improve fatigue life and fatigue strength for metal parts.

Laser peening can typically create these beneficial stress patterns 1-2 mm deep from the surface, 10 times deeper than conventional treatments, such as shot peening.

Moving the beam, not just the part

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.
