Waterjet Kerf Width

The waterjet kerf width is the width of the eroded gap, determined by the diameter of the abrasive stream and the lateral stream spread in depth.

Physical-Chemical Mechanism of Action

The kerf width in water jet cutting results from the erosion effect of the water, mixed with fine abrasive. The jet erodes the material and forms a kerf of a certain width.

Metallurgical Relevance & Welding Risks

A kerf width that is too large can cause uneven deformation and stress distribution, leading to cracks or splintering in the workpiece. A kerf width that is too small may not erode the material enough, resulting in incomplete cuts.

Shop Practice & Action Guidelines

Make sure the abrasive jet is set up correctly: a nozzle diameter of 0.5 to 1 mm and a sideways jet spread in depth of 2 to 3 mm. Check the kerf regularly and adjust the settings accordingly.
