Abstract: A system comprises one or more image sensors, processing circuitry, and communication interface circuitry. The image sensor(s) are operable to capture an image of a weld in progress powered by welding equipment. The processing circuitry is operable to, while the weld is in progress, analyze pixel data of the image, generate a welding equipment control signal based on the analysis of the pixel data, and output the generated welding equipment control signal via the communication interface circuit. The image sensor(s), processing circuitry, and communication interface circuitry may be integrated into welding headwear. The processing circuitry may be operable to determine, from the analysis of the pixel data, one or more welding parameters for the weld and to compensate for variations in the parameters by varying the welding equipment control signal to vary the welding equipment settings.
