چکیده مقاله
The smart materials revolution, driven by nanotechnology, is fundamentally transforming the paradigms of quality control and integrity assurance in welding engineering This review paper provides a systematic examination of the role of nanostructured sensors and novel non destructive testing NDT methods in evaluating nano engineered welds As base metals and filler materials become increasingly nano engineered, the need for inspection methods with nanoscale sensitivity becomes more critical In this context, sensors based on carbon nanotubes, metallic and piezoelectric nanoparticles, and nanocomposites enable real time structural health monitoring SHM and the detection of incipient cracks from within the joint itself Concurrently, nanomaterials are emerging as performance enhancers in classical NDT methods; from superparamagnetic nanoparticle suspensions in Magnetic Particle Testing MPT for detecting nanoscale cracks to nano carrier contrast agents in Ultrasonic Testing UT for high resolution imaging This review demonstrates that the convergence of these two paths intrinsic smart sensing and advanced external testing—is creating a new generation of self aware and self monitoring welded joints The reliability, lifespan, and safety of these joints in critical applications are qualitatively enhanced Finally, the challenges related to scalability, standardization, and integration of these technologies are discussed
