Comprender el corte láser de acero

El Corte láser de acero es un proceso de fusión, combustión o evaporación de materiales de acero utilizando rayos láser enfocados para lograr un corte preciso. El haz láser es generado por un resonador láser y guiado a la cabeza de corte a través de una serie de espejos o fibras ópticas. La cabeza de corte enfoca el rayo láser en la superficie del acero, donde transmite un fuerte calor para lograr el corte necesario.

Tipo de máquina de corte láser

1. las máquinas de corte láser CO2 utilizan una mezcla de gas dióxido de carbono para producir rayos láser. Son adecuados para cortar placas de acero más gruesas y tienen una excelente calidad de Corte.

2. Fiber Laser Cutters Fiber laser cutters use optical fibers doped with rare-earth elements to produce the laser beam. They are highly efficient and ideal for cutting thin to medium-thickness steel sheets with high precision.

3. NdYAG Laser Cutters These machines use a neodymium-doped yttrium aluminum garnet crystal to generate the laser beam. They are versatile and can cut various materials, including steel.

Techniques in Steel Laser Cutting

1. Fusion Cutting This technique involves melting the steel material with the laser beam and using a high-pressure gas to blow away the molten metal. It is suitable for cutting thin steel sheets and produces clean edges.

2. Flame Cutting In flame cutting, the laser beam heats the steel to its ignition temperature, and a stream of oxygen is introduced to burn the material. This method is effective for cutting thicker steel sheets.

3. Sublimation Cutting Sublimation cutting uses the laser beam to vaporize the steel material without melting it. This technique is used for cutting very thin steel sheets and produces minimal heat-affected zones.
