Process Testing method for materials in which a carbide ball is pressed down against the surface and creates an indentation which is measured to estimate the material’s Brinell hardness.
Process Cutting method in which an electrically charged wire is fed through a workpiece creating an electric discharge that cuts a contour in its horizontal plane.
Process Testing method for materials where a coil is charged with an alternating current to create eddy currents, which differ and indirectly detects when there is a defect in the material surface.
Process Testing method in which an initial crack is subjected to a force or a bending moment so that the material's fracture toughness can be determined.
