What Is Laser Cleaning?

Laser cleaning is an effective method to remove dirt particles and films of different materials and sizes on solid surfaces. Laser cleaning is to form a laser beam with a specific spot shape and energy distribution after optical focusing and spot shaping of a continuous or pulsed laser with high brightness and good directionality. After the contaminant material absorbs the laser energy, it will produce a series of complex physical and chemical processes such as vibration, melting, burning, and even gasification, and finally make the contaminant detach from the surface of the material. Even if the laser acts on the cleaned surface, most All are reflected off, and will not cause damage to the substrate, so as to achieve the effect of cleaning.

What Is Laser Cleaning Machine?

A laser cleaning machine is an eco-friendly power cleaning tool for surface treatment with handheld laser cleaning gun or CNC controller. A laser welder is used to remove rust, coatings, paint, oil, oxides, grease, resin, glue, dust, stains, residues, and more surface materials through instant high temperature ablation generated by laser beam on the surface of an object. Laser cleaning machines are also known as laser cleaners, laser rust removal machines, laser rust cleaning machines, laser paint stripping machines, laser paint removal machines, laser coating removal machines, laser oxide removal machines, laser oil cleaning machines, laser dirt cleaning machines, laser descaler machines.

Why Use Laser Cleaning Technology For Rust Removal

What materials can be laser cleaned?

Common Laser Cleaning Uses for Metal

Rust Removal

One of the most common uses of laser solutions is removing rust. This is done to prepare for welding or bonding prep, improve efficiencies, or restore products like historic builds to their former glory. The most common metals that can rust, include:

· Iron

· Cast Iron

· Wrought Iron

· Steel

Oxidation Removal

While laser cleaning is an effective means for removing rust, it also works on metals that don't contain iron but still develop an oxide coating. Oxides can alter the integrity of your product and create a protective layer. While this sounds positive, what's actually happening is that your product is breaking down, and removing that oxidation layer will expose it to further deterioration. Laser cleaning not only removes that protective layer, but it also removes the contaminant oxides altogether from your product — protecting it from further damage. The most common metals without iron include:

· Aluminum

· Bronze

· Copper

· Gold

· Platinum

Weld/bonding Prep

Contaminants such as oxides, grease, mold, and paint can prevent parts from welding or bonding together. This impacts the strength of your product in a big way. Laser cleaning removes even the thickest of contaminants from the surface of your product without impacting the integrity of the substrate — allowing you to secure parts with welding or bonding.

Hazardous Paint Removal

Removing paint can be a long and dangerous process — especially when working with chrome- or lead-based paints. Because laser cleaning uses pulses to absorb and remove contaminants, you can safely remove hazardous paint from your metal applications without creating additional waste or risking the safety of your operators.
