How Does Laser Cleaning Work in 5 Steps
Laser cleaning is a revolutionary surface treatment technology that uses a laser cleaning machine to remove contaminants such as rust, paint, grease, or oxide layers from metal, stone, and other materials. It is a non-contact, eco-friendly, and highly precise cleaning method widely used in manufacturing, aerospace, automotive, and restoration industries. Here is how laser cleaning works, explained in five simple steps. 1. Energy Absorption When the laser cleaning machine emits a focused laser beam onto the surface, the contaminant layer absorbs most of the laser energy while the underlying base material reflects it. The difference in absorption rates allows the laser to target only the unwanted layer. The contaminant heats up rapidly as it absorbs the laser pulse, while the substrate remains safe and undamaged. 2. Thermal Expansion and Stress As the contaminant layer absorbs energy, it undergoes rapid thermal expansion. This expansion causes high internal s...
