New Animated Video from LSP Technologies Illustrates ‘How Laser Peening Works’

Using a combination of live action and slow-motion animation, the video presentation helps us look at laser peening's startling impact at a microstructural level. Focusing on how laser peening improves the useful life of a crankshaft, the video demonstrates how laser peening deters corrosion and cracking.

LSP Technologies, Inc., the leader in laser peening technology, equipment, and services, has released a new video, “How Laser Peening Works,” to explain the laser peening process and how its patented surface treatment process adds years of useful life to many mission-critical metal components.

The video, available on the company’s YouTube channel (link) and on its website (link), uses live action and animation to examine how laser pulses provide beneficial compressive residual stress to prevent corrosion and cracking in key parts, using an automotive crankshaft as example.

“The new video presentation shows our Procudo® Laser Peening System in action, as well as some close-up animation at a microscopic level of how the laser peening process works under the surface of metal,” said Dr. Jeff Dulaney, President, CEO and founder of LSP Technologies.

“This is particularly helpful in communicating the essence of laser peening technology for engineers, production managers, and product development specialists. We believe many scientists and engineers involved in metal surface improvement technologies will refer to the video, too,” Dr. Dulaney said.

The video animation, produced by Vital Companies of Columbus, Ohio, demonstrates how laser peening can protect a crankshaft from metal fatigue at typical stress points, a process that can be adapted to many crucial metal components, even for hard-to-reach components, maintenance operations, and hazardous environments.

Manufacturers use laser peening in a wide array of parts for aerospace, heavy equipment, power generation, metal forming, shipbuilding and maintenance, and automotive applications. Laser peening can serve as a precise and cost-effective alternative to shot peening and other metal surface technologies that rely on heat processes or chemicals.

In laser peening, precisely controlled laser pulses create a small plasma explosion between the part and a smooth water overlay, which points pressure deep into the part. Video animation of what goes on below the metal surface shows how that plasma pressure expands the volume of the affected metal, producing the benefits of compressive residual stress.
