When working with galvanised steel, stainless steel, or aluminium, nitrogen laser cutting is most commonly employed. The laser beam melts and cuts the material during the cutting process, and the gas is required for cleaning, often known as “blowing out the melted material.” The enhanced power and pressure are what set this process apart from other laser cutting processes with oxygen.
When treating thin sheets where there is a risk of beam reflection, nitrogen is frequently advised. It aids in maintaining the cutting components’ flawless accuracy and repeatability. When employing nitrogen, the breadth of the material removed is usually less than 0.5 mm, which has a good impact on the amount of material lost and the efficiency of sheet disposal. We usually use nitrogen to cut sheets with a maximum thickness of 3 mm. Due to the amount of nitrogen needed, laser cutting thicker sheets is not profitable.
