AUTOMATIC BEVELING INSPECTION DEVICE

Japanese Patent JP2630717

B2

PURPOSE: To measure the thickness of a beveling as well as root face by obtaining the cross-sectional form of the beveling by an optical device, an image sensing device, and a surface form estimating device, and the plate thickness of a base metal by a ultrasonic 1' plate thickness gauge, and by synthesizing the cross-section form of the beveling from these both data.
CONSTITUTION: A laser beam 3 is led from a light source 4 to a beveling 2 of a welding base metal 1 through an optical fiber 6, and applied from a lens assembly 7 to focus an irradiation image by an image sensing device 5. After the image data has been binary-processed in an image processing device 8, it is transferred as a surface form data to a coordinate calculation device 9. Also a ultrasonic probe 11 of a ultrasonic plate thickness gauge 10 is located near the beveling 2 of the welding base metal 1, the plate thickness near the beveling 2 of the welding base metal 1 is measured by the ultrasonic plate thickness gauge 10, and the plate thickness is transferred to the coordinate calculation device 9. In the coordinate calculation device 9, the form coordinate of the beveling 2 is calculated from the surface form data and plate thickness to estimate the cross-section form of the beveling 2.
