It is now well known that laser cutting of steel is the most effective and appropriate method of processing this material. Laser cutting works very well when working with materials such as black, stainless, or galvanised steel. This is the most modern option, especially against the background of quite outdated cutting variants such as mechanical cutting or cutting with a torch. Laser cutting is, apart from cutting with a water or plasma beam, one of the most popular methods of cutting not only steel, but also other brass, copper, or aluminium materials..
