Sheet metal laser cutting is a non-contact machining process that uses a high-energy-density focused laser beam to irradiate the metal sheet, causing localized melting or vaporization. A high-pressure assist gas is simultaneously applied to blow away the molten metal, forming a narrow kerf.
Working Principle
The cutting mechanisms can be classified into two main types: Fusion Cutting: Uses nitrogen or argon as assist gas to blow away molten metal. Suitable for stainless steel, aluminum, copper, and similar materials. Oxidation Cutting (Flame Cutting): Uses oxygen as assist gas, which reacts with iron to produce combustion, thereby increasing the cutting speed of carbon steel.
