Abstract
There is described a marking method for distinguishing the kind, depth, position and area of surface defects of a metal piece as well as a method for detecting marks on the metal piece and a method for arranging detected signals in a electronic computer to automatically control scarfing. Shapes and colors of the marks respectively correspond to either the kind or depth of the surface defects of the metal piece. The marks are detected by a photosensitive means which can recognize colors of the marks, for example, industrial color television camera. Output signals of the camera are transmitted to the electronic computer. The computer arranges the signals and processes them to automatically control the scarfing machine.
