Before the popularization of laser cutting technology, traditional processing methods such as plasma cutting and flame cutting were mostly used for sheet metal cutting, which had many shortcomings, such as wide cutting slits, poor cutting accuracy, easy generation of harmful gases, and large environmental pollution. After the promotion of laser cutting technology, laser processing began to replace traditional processing methods with many advantages such as high precision, less deformation, good effects, fast speed, low consumables, and green environmental protection.
However, in terms of thick plate cutting, the processing thickness of kilowatt lasers still has limitations, so that thick plate cutting still needs to rely on plasma cutting. After the launch of the 10,000-watt laser, the thickness of the cuttable sheet has continued to break through, and the processing efficiency, cost, effect and other aspects are also superior to traditional cutting methods such as plasma cutting, instantly capturing the "hearts" of a large number of end users.
Comparison of cutting methods | |
10000w laser cutting | Plasma cutting |
The cutting speed is fast, the air cutting efficiency is maximized | Low energy density, slow overall cutting speed |
Low cost of equipment consumables and few wearing parts | The cost of consumables is high, and the entire cutting torch (nozzle, swirl ring, electrode, etc.) needs to be replaced within a few hours |
High cutting precision, small taper of thick plate | The thick plate has a large cross-section taper and requires secondary processing |
Small heat-affected zone, no deformation of the plate | Large heat-affected zone, easy deformation of the plate |
Small kerf, high sheet utilization | Large kerf, more material left |
Small holes can be cut, the diameter can reach 20%-50% of the thickness | Cannot cut small holes, need secondary processing |
Basically dust-free, green and environmentally friendly | Big smoke and dust, serious pollution |
