Laser cleaning, also known as laser material removal, is an advanced method of removing surface materials by precisely manipulating and scanning a laser beam. This process utilizes laser thermal shock to effectively strip, evaporate, sublimate, or burn off unwanted waste without causing damage to the substrate. Laser cleaning is widely used in various industries to remove unwanted surface materials such as coatings, paints, rust, oil stains, as well as surface treatment for welding and coatings.

Careful optimization of laser parameters ensures processing without damaging the underlying surface. The non-contact nature of laser cleaning makes the process highly reproducible, minimizes the generation of toxic waste, and enables precise control of surface treatment effects. Accurate laser aiming can ideally control the shape and size of the material removal area.

1. Although abrasive spraying is usually effective, it is noisy and requires the collection and treatment of the spraying medium, resulting in high costs. Fiber laser does not require consumables and can provide more flexible and controllable processes.

2. Dry ice blasting avoids the problem of medium handling, but still has high noise, high cost, and poor effectiveness in some applications. Laser cleaning is easier to control the processing of small components and has lower operating costs.

3. Chemical cleaning is not easy to apply to selective areas and requires expensive solvent treatment. Fiber laser cleaning can provide simple selective targeting without the need for handling chemicals or partial drying time.

4. Hot cleaning usually requires excessive heat to be effective and may cause damage to the underlying substrate. Fiber laser cleaning is faster, more energy-efficient, and can process more materials while reducing heat input.
