10kW+ Fiber Laser Cutting: Revolutionizing Thick Metal Processing in Heavy Industries
Before the rise of 10,000-watt laser cutting equipment, laser processing of metal sheets was mainly thin plates (1-15mm), that is, laser cutting equipment of 4KW and below, such as elevator plates, alloy materials, doors and windows, lighting, metal kitchenware, hardware products, etc. However, with the emergence of 10kW laser cutting machines, the thickness of metal cutting has been continuously broken. Fiber laser cutting technology with a power of 10kW and above is achieving a revolutionary breakthrough in the processing of thick metal plates in multiple industrial fields with its high energy density, excellent beam quality and flexible processing capabilities.
This article will deeply explore the application of 10kW laser cutting in engineering machinery, shipbuilding, energy equipment, rail transportation, aerospace and steel structure buildings, and analyze in detail the cuttable thickness range, process parameters and industry cases of different metal materials, providing a comprehensive technical reference for manufacturing users.
Why Choose 10kw+ Fiber Laser Cutting?
Today, as industrial manufacturing moves towards intelligence and efficiency, 10kW+ fiber laser cutting technology is reshaping the pattern of thick metal plate processing with revolutionary advantages.
Higher cutting efficiency
The increase in power has brought reforms to the sheet metal processing industry. In addition to being able to process thicker materials, its efficiency has also made a qualitative leap. Data shows that when processing aluminum alloys, the speed of 12KW laser cutting machines is significantly improved compared to 10KW. Especially when cutting 25mm thick plates, the cutting speed can be increased by 100%. On the other hand, when cutting 5-12mm brass, the cutting speed of the 12KW laser cutting machine is more than 100% higher than that of the 10KW. It can be seen that the increase in laser power is obvious for the increase in cutting speed.
Better cross-sectional quality
The 10,000-watt laser cutting can achieve a smaller taper with high beam quality and intelligent focus control. The cutting taper when cutting 20mm stainless steel is less than 0.5°, and the taper of 40mm carbon steel is less than 1°, which is better than plasma cutting (usually >3°). In addition, when cutting stainless steel with nitrogen, the 12kW laser can make the slag thickness less than 0.1mm, which directly meets the welding requirements.

Lower overall cost
Although the initial investment in laser cutting equipment is high, the long-term cost of 10kW laser has significant advantages. This is due to the fact that fiber laser cutting is superior to traditional cutting methods such as plasma and water jet cutting in terms of energy consumption, consumables, labor costs, and secondary processing costs. Therefore, in the long run, the overall cost of fiber laser cutting is lower.
More process breakthroughs
Compared with low-power laser cutting equipment, 10,000-watt lasers have promoted advanced processing technologies, such as intelligent perforation technology that can penetrate 30mm carbon steel in 3 seconds, laser cutting-beveling-drilling integrated composite processing methods, and thick plate continuous cutting technology.
