Abstract: Disclosed herein are systems and methods for identifying welding anomalies and discontinuities using AI models. Instead of conventional welding accuracy methods (e.g. destructive and/or image generation methods) a processor may communicate with one or more sensors associated with a welding machine to retrieve welding data and attributes.

The processor may execute the AI model using data retrieved from the sensors and may calculate a likelihood of a discontinuity and discontinuity attributes, such as, location, depth, and the like. The processor may then display a visual representation of the discontinuities calculated using the AI model.
