Summary

Dynamic Tech Nears Test on World Stage

Ohio-based LSPT – its name stands for Laser Shock Peening Technologies – will in the first quarter of 2018 test the use of exploding vapor from water heated by a laser beam to create tiny deformations in the surface of materials used to build aircraft, to improve crack propagation – and therefore fatigue behavior – in the area. This technology would improve upon shot peening. Today, manufacturers commonly shoot metallic particles at the surface of materials used to build aircraft. The manual process is commonly used in aerospace, despite the fact that it is not terribly precise. The proving ground for laser shock peening? A public-private-partnership in Hamburg, Germany, called the ZAL TechCenter.

LSPT engineers pioneered the laser peening process at Battelle Memorial Institute, and helped the United States Air Force solve critical fatigue problems on titanium turbine blades in the B-1 bomber.

LSPT designed and built the world’s first laser-peening equipment and remains the only company in the world selling, installing and integrating comprehensive laser peening system into customer facilities.

Fatigue threatens all metal load-bearing components. High-cycle fatigue (HCF), foreign object damage (FOD), and stress corrosion cracking (SCC) exacerbate material cracks and flaws – shortening service lifetimes and endangering critical parts to failure.

Laser peening is a powerful metal improvement solution using high-energy laser pulses to enhance metal fatigue strength and damage tolerance. Laser peening produces material benefits up to 20X deeper than shot peening, and has applications across the aerospace, automotive, power generation, tooling, medical, and defense manufacturing industries.

This webinar will cover:

•An overview of Laser Shock Peening: how it works, the material benefits and industry applications.

•Advances in laser peening equipment and technology that have increased throughput and process control for high-volume production processing.

•The next generation of laser peening applications, highlighted by advanced development at the ZAL TechCenter in Hamburg, Germany.
