Kerf Geometry
Kerf geometry describes the spatial profile and dimensional accuracy of the gap that results when cutting workpieces. It influences the accuracy and stability of subsequent joining processes.
Physical-chemical mechanism of action
The kerf geometry refers to the spatial profile of the gap created when cutting workpieces. This gap can be produced by mechanical or chemical processes such as cutting, laser, or plasma removal.
Metallurgical relevance & risks in welding
Inaccurate kerf geometry can lead to joining errors and a reduction in mechanical properties. Gaps that are too narrow or too wide can deform the material, cause porosity, or impair the strength of the joint.
Workshop practice & instructions for action
To ensure accurate kerf geometry, the cutting processes must be precisely controlled. This involves selecting the right cutting process, correctly setting up the machines, and monitoring process parameters such as temperature, pressure, or laser peak power. For complex workpieces, it is advisable to carry out prototype development before cutting to determine the optimal settings.
