Rust can be a pesky problem for industries and individuals alike — no one understands this better than the team here at Dustless Blasting. The traditional methods of cleaning metal surfaces and rust removal in general are known for being time-consuming and messy. Among the more modern and efficient solutions gaining popularity for rust removal is laser cleaning. In this blog post, we will explore what laser cleaning is, how laser light rust removal is possible, where to source a laser light rust remover and the pros and cons of pursuing this solution for personal or business projects.
What is Laser Ablation?
Laser ablation is the removal of material from a surface by evaporation or sublimation. This process is achieved by depositing energy on the surface via a pulsed or continuous laser, which thereby removes the material by vaporizing it. This technique is widely used in manufacturing for cutting, engraving, and creating patterns on materials. It also has the ability to be used in medical applications such as removing layers of skin or tissue. The focus here is more on precise material removal for shaping or modifying an object.
What is Laser Cleaning?
Laser cleaning refers to the removal of contaminants from a surface through the process of laser ablation. As a non-contact cleaning method, laser cleaning is an environmentally friendly and efficient way to clean surfaces without damaging the underlying substrate.
By using a focused laser beam, this method can remove paint and oxide layers from metal surfaces or build up on historical monuments. The goal is to do this in a way that is non-abrasive and precise with little mess or cleanup and no negative affects to the environment.
What is the Difference Between Laser Ablation, Laser Cleaning & Laser Rust Removal?
Laser ablation is the more technical term for the removal of material layers off a solid surface. Laser cleaning is a form of laser ablation and is used as a broader term that refers to the removal of contaminants from surfaces using a laser beam. Laser rust removal is a specific application of laser cleaning, focused on removing corrosive substances from metal surfaces.
How Does Laser Cleaning Work?
To remove contaminants with a laser cleaning tool, simply point the high-intensity laser beam at the rusty surface and let the magic happen — and it does look like magic! The energy is absorbed by the rust, causing it to heat up and evaporate. This leaves behind a clean surface without the need for harsh chemicals or manual scrubbing. And, it eliminates the mess. Because the contaminants absorb light from the laser and break down into a gas, the released particles can be captured via air filtration systems or vacuums.
Benefits and Drawbacks of Laser Rust Removal
Benefits of Laser Cleaning Equipment
Laser rust removal is faster and more efficient than many traditional cleaning methods, which can be time-consuming and labor-intensive. It eliminates the need for harsh chemicals and abrasive materials, making it a safe product for the environment with minimal or no secondary waste creation. By providing a clean, bare metal surface, it is an effective way to extend the lifespan of metal products and reduce maintenance costs. The technology and process is highly precise and controlled, which means it can be adjusted to suit different materials and levels of contamination. Laser cleaning is ideal for delicate surfaces and hard-to-reach areas, but it might not always have the bandwidth to cover a large surface area quickly.
In regards to safety, this surface preparation method involves little to no risk for the user and the material, as long as safety precautions are acknowledged. It is, however, advisable to enroll in training for operating a laser. While it is general deemed safe, the use of safety enclosures and personal protective equipment, primarily safety glasses and gloves, is recommended.
Drawbacks of Laser Cleaning Equipment
Laser cleaning equipment is not as versatile of other surface restoration machines on the market. For example, combustible materials such as wood should never be used with or near a laser, as its heat output has the potential to start a fire. If you're needing a system that can restore a variety of surfaces, consider looking at Dustless Blasting equipment.
Additionally, the cost of investing in this equipment for extremely niche applications is often times a deal breaker. To read more about these machines, click here for our blog on Laser Cleaning Equipment.
Laser Cleaning FAQs
What Equipment is Used for Laser Rust Removal?
Laser light rust removal machines can be purchased from specialized manufacturers and distributors. They come in various sizes and configurations, but it is important to note that a high-powered laser beam is necessary for effective rust removal and the removal of built-up debris, and with power comes a higher price.
Which solution is best to remove rust from my car?
Laser rust removal is best suited for automotive manufacturing operations with large production quantities or repeated tasks. It is safe on sensitive surface materials and can reach smaller, targeted areas. The blast pattern of a laser can be relatively smaller in size, meaning that laser cleaning may take longer to finish a project than any rust removal methods, like Dustless Blasting.
Dustless Blasting is another popular method for removing rust and other contaminants from surfaces, particularly in the automotive industry. To learn more about the differences between Dustless Blasting and laser cleaning and why you might consider one over the other, click here.
What does a laser cleaning system cost?
The cost of a laser cleaning machine can vary widely depending on factors such as its power, size, brand and specific features. Typically, prices can range from a few thousand dollars for low-powered, smaller and more portable models to hundreds of thousands of dollars for large, industrial-grade machines.
