“…Casting is a manufacturing process finding applications in complex industries, such as aerospace [2], [35] and automobile [4], [36] industries, and with materials, such as aluminum [37], [38] and titanium [2] alloys. Due to the limitations of the manufacturing techniques [37], castings can host several defects, such as holes and flaws, gas cavities, shrinks, slags, cracks, high-and low-inclusions, wrinkles, casting fins, shrinkage-holes, and incomplete fusion [2], [35], [36], which can lead to catastrophic failures of critical mechanical components [4], [37]. Therefore, it is crucial to implement a non-destructive testing system to detect internal and surface defects early in the manufacturing process to reduce the risks and save time and costs [36], [38].…”
