The U.S. Army Yuma Test Center (YTC) at U.S. Army Yuma Proving Ground (YPG) has invested in a new Laser Ablation Cleaning System to significantly advance its capabilities in non-destructive testing (NDT), efficiency, and sustainability. The system’s initial application is to streamline the process of cleaning copper crusher gauges, a critical component in live-fire testing.
The system was brought to YTC by mechanical engineer David Le, a seasoned professional in the field of non-destructive testing, to enhance the cleaning process for the gauges. These gauges are used to measure the pressure of a round, and maintaining their integrity is paramount. The new system performs a crucial pre-testing function, preparing the gauges for repeated use and extending their life expectancy.
Bartek Dajnowski, president of GC Laser Systems and the system’s inventor, described the technology as “effective, precise and environmentally friendly.” He explained how it works: “Laser light is targeting the corrosion and the deposits on the copper crusher. The laser pulses are exciting the molecules of that contaminant. They get so excited that they shake themselves apart and eject off the surface.” The vaporized contaminants are then captured by a vacuum system.
The laser system provides a massive leap in efficiency. Daniel Henley with Mass Properties noted an "insane time difference," explaining that the previous method took about an hour, while the new laser cleans a gauge in just over a minute. The system can be set up to clean a full tray of gauges autonomously. Zac Pettigrew, also with Mass Properties, highlighted the long-term benefits for the equipment. "This system is going to eliminate having to put them in any kind of liquid. It’s going to give us another layer of life expectancy increase."
While the initial focus is on copper crushers, Le foresees a much broader application for the technology. "We project there could be several larger applications that we could use on weapon systems or test vehicles before engaging in non-destructive testing, painting, or welding.” This investment underscores YTC’s commitment to adopting advanced NDT technologies that reduce manual labor, improve safety, and ensure the precision of its testing operations.
