PURPOSE:To scarf away automatically the defective part on the surface of a metallic material in the stage of removing by scarfing the defective part on the surface of the metallic material by detecting the spark in the defective part owing to radiation of a scarfing flame with an image pickup device and moving a scarfer to the defective part according to the result thereof. CONSTITUTION:While a metallic material 1 such as a steel billet or the like is conveyed on rollers 2 in an inspection part A, a flame is injected from a scarfer 5 attached to a traveling carriage 4 movable on traveling rails 3 atop the material and the luminance thereof is taken with a television camera 6. The operation is performed over the entire surface of the billet 1 and the defective spark generated in a defective part such as slag inclusion, pinhole or the like is detected. The billet 1 is then fed to a scarfing and mending part B, where a conveying roll 2' and a geared motor 10 for driving are controlled by the detection signal of said defective spark to adjust the conveying speed of the billet 1; at the same time, the defective part is automatically scarfed away by a scarfer 9a in the part B.
