Types of laser cutting in the manufacturing industry
Laser cutting is the process of cutting a material using a laser beam. This process can be done to either trim down a material or to help cut it into complex shapes that more conventional drills would struggle with. Lasers are basically just highly focused beams of light. This beam of light means concentrated energy, and this will cause things to heat up.
With the developments of modern technology, a single laser beam is now powerful enough to cut through wood, plastics and metals and as such, laser cutting has helped to revolutionise much of the manufacturing industry.
Laser cutting is now becoming somewhat of a standard tool in many industries because of the benefits it provides. A single laser beam is now powerful enough to cut through wood, plastics and even metals. As such, laser cutting has helped to revolutionise much of the manufacturing industry.
What types of lasers are being used in the manufacturing industry?
As the energy from the laser heats and melts the material, a co-axial jet is used to help expel the molten material. This creates a slit or notch in the material and allows us to cut through material with relative ease and with incredible precision. There are three main types of co-axial jet used in laser cutting.
1. Fusion Laser Cutting
Fusion laser cutting uses a jet of inert gas to help expel the molten material from the kerf to complete the cut. An inert gas such as nitrogen is typically used for this task. Nitrogen does not react to the heat of the molten material meaning it only contributes to helping force the molten material from the kerf physically.
2. Flame Laser Cutting
Flame laser cutting is similar to fusion laser cutting, only a different type of gas is used. The gas used for this task is typically oxygen and oxygen will react to the heat of the molten material. This adds more energy to the process which helps with the cutting in addition to physically forcing the molten material from the kerf.
3. Remote Laser Cutting
Remote laser cutting does not use assistance from a co-axial jet of gas. Instead, it uses a laser beam of a higher intensity that is able to partially evaporate the material. This process is often used on thin sheets of material.
The type of laser process that you will use will depend largely on the job at hand and the tools available to you. Regardless of which specific method you use, laser cutting offers precise and relatively easy cutting of a range of materials. It can also be used on a range of materials, and on jobs of all sizes.
