CO2 Versus Fiber: Considerations for Laser Cutting Choices

Laser cutting is a mainstay technology in industrial and metal manufacturing applications. The computerized and therefore highly accurate method works by focusing the output of the laser at the material to be cut, melting, burning, vaporizing, and blowing it away (by a jet of gas) to leave a high-quality surface finish. Industrial laser cutters are typically employed in the cutting of structural,...
