What is Laser Cutting?

Before diving into its applications in the automobile manufacturing sector, let's briefly understand what laser cutting is. Laser cutting is a technology that uses a high-powered laser beam to cut through materials with incredible precision.

It's a non-contact process that can cut through a wide range of materials, including metals, plastics, and composites.

The key components of a laser cutting system include the laser source, focusing optics, and a computer-controlled machine that directs the laser beam.

The laser beam is focused on the workpiece, and the intense heat generated by the laser vaporizes, burns, or melts the material, leaving a clean and precise cut.
