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 then execute an AI model that is trained based on previously performed weldments, their corresponding welding attributes, and their corresponding discontinuities and/or anomalies. 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.
