Advanced active thermography for weld joint inspection

Abstract. Ensuring the integrity and mechanical performance of critical components is essential in many industrial applications. Widely used inspection methods have several limitations: destructive testing is accurate but involves sample destruction and time-consuming procedures, ultrasonic testing is slow and requires contact and skilled operators, and radiographic testing is expensive and demands stringent safety measures. This work presents an innovative non-destructive inspection method based on active infrared thermography. Modulated heat sources locally heat the specimen while advanced algorithms process the resulting thermal images to generate high-contrast maps for rapid defect detection and material characterization. Its cost-effectiveness and ease of integration into in-line production processes make it highly suitable for automotive, aerospace, and high-precision manufacturing applications.
