1. The Shift to High Wattage Fiber Cutting

For decades, heavy plate fabricators processing steel above 25mm relied almost exclusively on CNC plasma and oxy-fuel cutting systems. However, with breakthroughs in 30kW, 40kW, and 60kW high-brightness fiber laser sources, the economics of plate processing have fundamentally changed.

2. Slag-Free Piercing & Edge Quality

Plasma cutting creates a heat-affected zone (HAZ) of up to 3mm and an edge bevel of 2–5 degrees that requires secondary grinding or machining before welding. Fiber lasers, by contrast, deliver straight 90° kerf walls with zero dross and instantaneous flash-piercing.

3. Gas Cost Reduction

Using ultra-high pressure air cutting technology, modern fiber lasers reduce nitrogen and oxygen dependency, cutting cutting-gas costs by more than 40% while achieving up to 300% faster feed rates on medium-to-thick plates.
