Advantages And Disadvantages Of Fiber Laser Cutting


  • Narrow cutting groove, the cutting surface can be directly used for welding without grinding.
  • Fast cutting speed: The cutting speed of thin slices can reach 10m/min, which is much faster than plasma cutting.
  • Good cutting quality: small deformation, low surface roughness, low cutting edge slope.
  • High accuracy: positioning accuracy can reach 0.05mm, repositioning accuracy can reach 0.02mm


  • High cost: Both initial investment and subsequent maintenance require high costs.
  • Low efficiency: At present, fiber laser cutting of thin plates is more cost-effective. However, when cutting thick plates, the efficiency is low, so unless the quality requirements are high, it is not suitable for fiber laser cutting.

Advantages And Disadvantages Of Plasma Cutting


  • In the process of cutting medium and thick plates, it can reach a very high cutting speed, much higher than laser cutting and flame cutting.
  • The initial equipment investment is lower than the laser, and the subsequent maintenance cost is much lower.


  • The verticality of the cutting surface is poor: the side of the cutting surface will have a large inclined cutting edge, and the verticality will be very poor.
  • Produce more cutting slag: Cutting slag will be generated at the bottom of the cutting surface during the cutting process. In order not to affect the quality of post-processing, this slag must be removed by grinding, which also increases labor costs.
  • Generate harmful gas and arc light: The principle of plasma cutting determines that harmful dust and arc light will be generated during the cutting process. However, underwater plasma cutting is also used to avoid this defect.
  • High cost in the later stage: More cutting nozzles are consumed in the later stage, and the cost is very high.
