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.

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.

Register for the March 20 webinar now

Laser peening solutions typically extend the fatigue life of parts by five to 10 times their normal useful life, and some parts can last as much as 20 times longer.

We’ll discuss:

  • How the laser peening process works
  • How LSP Technologies develops custom solutions for parts
  • How to prevent, mitigate, or arrest cracking and corrosion
  • What kind of life extension is possible
  • Return on Investment

How we develop solutions for metal parts

LSP Technologies focuses on customers, their parts, and the operational stresses that threaten the fatigue life of metal alloys, such as cracking, corrosion, or stress from pressurized water.

Large cam shaft
Large cam shafts can benefit from laser peening.

Our application development process puts our engineering team at your disposal. For a modest price, we examine your component, model how it might best react to laser peening, and prescribe a carefully designed solution.

How do we meet your deadlines and produce the results you require? We have more than 20 years of experience in producing laser peening solutions.

That means we have built an extensive library of metal alloys and the the kind of power, spot size, and other parameters in order to produce optimal results.
