SYNCHRONIZED IMAGE CAPTURE FOR WELDING MACHINE VISION

摘要

An automated welding device comprises a camera, processing circuitry, a welding torch, and an electromechanical subsystem. The camera is operable to capture, using visible and/or infrared wavelengths, an image of one or more workpieces. The processing circuitry is operable to synchronize the capture of the images to times when voltage between the welding torch and the one or more workpiece is below a determined threshold. The processing circuitry is operable to process the images for determination of physical characteristics of the one or more workpieces. The processing circuitry is operable to generate, during welding of the one or more workpieces by the welding torch, electrical signals which are based on the determined physical characteristics of the one or more workpieces, and which control one or more welding parameters of the automated welding device during the welding of the one or more workpieces.
