The main advantage of cutting with water (WaterJet) is the fact that the material does not heat up during cutting, i.e. there are no changes in the structure of the material caused by heat treatment. Depending on the thickness of metal sheets / elements, cutting with pure water under pressure or water with an abrasive additive is used. Water Jet cuts both thin and thick materials very well, but it does not deal with complicated geometries – water cutting can be used to cut rather simple shapes.
