Learn how fiber laser cutting technology works, its applications, and how it supports precision and efficiency in metal fabrication.

1. What Is Fiber Laser Cutting?

Fiber laser cutting is a thermal cutting process in which a high-energy laser beam is generated through an optical fiber and focused onto a material’s surface.

The concentrated energy heats and melts the material, while an assist gas helps remove the molten material to create the cut.

This process is commonly used for cutting metals such as stainless steel, mild steel, aluminum, and other compatible materials.

2. How Does Fiber Laser Cutting Work?

The fiber laser cutting process generally involves the following steps:
