In the construction industry, lasers are commonly used for various purposes such as surveying, leveling, alignment, and cutting. The most powerful lasers allowed in construction depend on the specific application and safety regulations in the region where the construction is taking place.
For example, in surveying and leveling applications, laser levels with a Class 3R or Class 3B laser may be used. These lasers emit low to moderate power beams that are generally considered safe for use with proper precautions. They are used for tasks like setting grades, aligning walls, and ensuring level foundations.
In construction cutting applications, particularly for materials like steel or concrete, more powerful lasers may be used. Fiber lasers, for instance, can be quite powerful and are used for cutting metal sheets and plates in various thicknesses. The power output of these lasers can range from a few hundred watts to several kilowatts, depending on the specific requirements of the cutting task.
However, it’s important to note that the use of high-powered lasers in construction is subject to strict safety regulations to prevent accidents and ensure the well-being of workers and bystanders. Regulatory bodies such as OSHA (Occupational Safety and Health Administration) in the United States and similar organizations in other countries impose limits on laser power levels and require safety measures such as safety interlocks, protective enclosures, and proper training for operators.
