LIFT inspects metallic workpieces with respect to the material grade automatically.
An intensive laser beam is focused onto the surface of the workpiece and evaporates a few microgrammes of the material. The generated plasma emits element-specific radiation, which is detected by a spectrometer. The data are evaluated in order to identify the material. LIFT is able to inspect more than 30 different material grades. The pipe fittings are of different shapes and sizes.
