Optimizing Laser Peening for High-Repetition-Rate Applications

Laser shock peening (LSP) has revolutionized surface enhancement, achieving new benchmarks in metal fatigue resistance and failure prevention. The laser peening process uses high-energy pulses to produce powerful shockwaves on the surface of metal components. These mechanical shockwaves plastically deform the material, producing compressive residual stresses that reach depths previously unachievable with peening and rolling technologies.

As laser peening gained adoption with gas and steam turbine manufacturers, aerospace and power generation customers have saved millions of dollars by achieving longer service lifetimes, reduced component failures, decreased inspection requirements and reduced maintenance costs. These performance benefits validate laser peening as a cost-saving industrial application to prevent part failure caused by fatigue cracking, stress corrosion cracking, or foreign object damage.

Where Does Laser Peening Fit in the Metal Finishing Process?

David Lahrman is a certified trainer for Metal Finishing News International (MFN). David provides insights and instruction on metal finishing for this worldwide network, and he wrote a feature article for the July 2017 issue of MFN Magazine.

MFN International – July Issue – 2017

Laser shock peening is a powerful, targeted method for enhancing metal fatigue strength using high-energy laser pulses. Like shot peening, laser peening imparts beneficial compressive residual stresses in the surface of a component to impede crack initiation and propagation. Unlike shot peening, laser peening is only applied to fatigue-critical areas to provide enhanced resistance where parts are most susceptible to failure. Laser peening is commonly applied along the edges of compressor turbine airfoils to protect against foreign object damage and erosion, or applied along the dovetail root to prevent fretting fatigue, stress corrosion cracking and fracture.

New diode-pumped system brings laser peening to the factory floor

Material enhancement has long been at the leading edge of technological innovation. Powerful machines require robust components, but material limitations present a critical obstacle to performance optimization. Laser shock peening (LSP) resides at the forefront of material enhancement, employing high-energy lasers to generate deep compressive residual surface stresses for proven metal fatigue resistance. Laser peening has been implemented by original equipment manufacturers (OEMs) in the aviation and power generation industries to enhance their products’ resistance to cracking caused by fretting, corrosion, foreign object damage, and fatigue. Now, after nearly fifty years of technological advancement, the first line of turn-key industrial laser peening systems is integrating the technology into manufacturing facilities around the world.
