Laser cutting or profiling is a well established production method in the steel and metals fabrication industry. It enables complex and precise cutting of steel and aluminium sheets to a very high quality finish which would previously have been prohibitively expensive to machine cut. It enables the manufacturer to laser cut small diameter holes with complex detail and good edge quality in either sheet, plate, tube or box section metal items.
The Laser Cutting process is blanketed with high pressure nitrogen as a shielding effect which eliminates oxidisation and improves edge quality and other finishing procedures. It also ensures that stainless steels does not lose its corrosion resistance and aluminium items have a burr-less finish. The laser cutting beam melts the material and in addition to its blanketing benefits, the high pressure nitrogen blows away the molten material and forces the metal to harden quickly.
