Removing the Oxidised Edge After Laser Cutting

Laser assist gases are used at the point where the laser cuts the metal and most laser cutting companies use either Oxygen or Nitrogen as the assist gas. Oxygen is excellent for cutting mild steel as it actually speeds up the cutting process and allows cutting speeds to increase.

Nitrogen can also be used for cutting mild steel although the speed benefits are not realised as the nitrogen does not actually assist laser cutting in the same way as oxygen does. However, laser cutting with nitrogen has one major benefit when compared to cutting with oxygen as it prevents an oxidised edge on the part. Whilst this looks aesthetically pleasing it also means that the parts can be painted without a descaling operation.

GF Laser offer nitrogen laser cutting for customers and have recently invested in a 30,000 litre tank to supply their fiber laser cutting machines with high quality nitrogen.

Working in conjunction with the large tank supply GF Laser also generate their own nitrogen using an advanced Nitrocube system that converts compressed air into nitrogen. This two-fold approach means that the laser cutting machines always have nitrogen available for cutting 24/7 to meet customer demand.

Our team of estimators can advise what type of gas is required for different projects depending on customer requirements. GF Laser can also carry out alternative methods of descaling such as manual deburring or barreling which is well suited to high volume batch production.
