Waterjet Cutting Comparison With Other Methods
Waterjets can cut any solid material including stone, tile, glass, metal, foam, rubber, plastic, and food. When compared with plasma, laser, and edm – waterjet cutting has distinct advantages.
WATERJET vs. Plasma vs. Laser vs. EDM
In addition to no heat-affected zone, the benefits and applications for waterjet technology are limitless and ever-expanding. In comparison to other cutting technologies:
|Process||Erosion process: high speed liquid sandpaper||Burning / melting process using high temperature ionized gas arc||Melting process using concentrated laser light beam||Erosion process using electrical discharge|
|Materials||Any material.||Primarily steel, stainless steel and aluminum.||Primarily steel, stainless and aluminum.|
Can also cut a variety of other materials.

As the grid above illustrates – and the image to the right shows, waterjet cutting technology has clear advantages over other cutting methods.
Waterjet cutting is a cold-cutting process that eliminates slag deformation and dross waste – unfortunate effects found in plasma and laser cutting processes.
Additionally, both the garnet used in abrasive cutting as well as the water are recycable.
