1.Introduction to Laser Cleaning

1.1 What is Laser Cleaning?

Laser cleaning is an advanced technology used to remove contaminants, such as rust, paint, oil, and other unwanted substances, from surfaces using a high-energy laser beam. This method involves directing a focused laser onto the surface, where it interacts with the contaminants, causing them to either vaporize or be ejected from the surface. The process is highly precise, non-contact, and non-abrasive, which makes it suitable for cleaning delicate and intricate surfaces without causing damage to the underlying material.

1.2 Applications of Laser Cleaning Technology

Laser cleaning technology is versatile and finds applications across various industries due to its precision, efficiency, and eco-friendliness. Some key applications include:

1. Automotive Industry:

   • Paint and Rust Removal: Laser cleaning is used to remove old paint and rust from car bodies and parts, preparing them for repainting or further processing.
   • Weld Cleaning: It is employed to clean welds, removing oxides and contaminants to ensure strong and clean weld joints.

2. Aerospace Industry:

   • Surface Preparation: Laser cleaning is used to prepare surfaces for bonding, coating, or painting, ensuring optimal adhesion and finish.
   • Maintenance and Repair: It is utilized for the maintenance and repair of aircraft components, removing contaminants without damaging sensitive materials.
