Using high-pressure nitrogen for laser cutting

In laser cutting the laser beam melts the material and high-pressure nitrogen forces the metal quickly to harden. As nitrogen has a shielding effect, the cutting area is protected against ‘bluing’ and oxidation.

Using high-pressure nitrogen for laser cutting of steel and metal has many benefits over alternatives such as oxygen.

Advantages of Nitrogen use in laser cutting

  • Protects the metal from corrosion.
  • No oxidation of the steel occurs.
  • No additional heat is generated.
  • A high quality (clean-cut) edge is achieved.
  • The clean cut makes it easy to weld and paint or powder-coat the metal.
  • Paint will not fall off the edges.
