“…Within the naval infrastructure, IRT has a high utility due to the large number of welded pieces. For instance, Crupi et al [59] apply a thermographic analysis to predict the fatigue behaviour of butt-welded joints, made of AH36 steel, which is widely used in shipbuilding.…”

Health monitoring and prediction in different types of structures is essential in order to maintain optimal conditions. Some of the pathologies that affect their structural stability are characterized by distinct thermal properties compared to unaltered areas. Infrared thermography (IRT) is a technique based on the acquisition of the thermal radiation of the bodies using thermal sensors of infrared (IR) cameras, which produce an image of the thermal infrared radiation captured through the conversion of the radiation values to temperature values. Therefore, this technique can be used in different studies to analyse structures with one or more pathologies based on their anomalous thermal behaviour with regard to the unaltered surroundings. As a consequence, this review presents various IRT applications to infrastructure inspections, showing the utility of the technique.

Friction Stir Welding has proven its merits for welding of aluminium alloys and is focused in expanding its material database to steel and titanium and also to assess new joint configurations. The use of welded structures in shipbuilding industry has a long tradition and continuously seeks for innovation in terms of materials and processes maintaining, or even, reducing costs. Several studies have been performed in the past years on FSW of steel. However, just recently were reported defect-free welds, free of martensite with stable parameters in steel without Primer. FSW of steel with primer has not been addressed. This work aims to fulfil a knowledge gap related to the use of friction stir for welding shipbuilding steel by analysing the effect of welding parameters on the metallurgical characteristics and mechanical properties of welds obtained with an innovative FSW tool in joining steel plates with a primer. Welds were performed in 4mm thick GL-A36 steel plates painted with a zinc based primer followed by a detailed microscopic, chemical and mechanical analysis. The results that matching fatigue properties are obtained using this technique, in FSW of shipbuilding steel with Primer.

“…Except for the above method, the one line method 19 is also widely used to predict the fatigue limits of materials by many researchers, such as Fargione et al, 20 Fan et al 21,22 and Crupi and coworkers. [23][24][25][26] Material and method…”

The relationships between the stress concentration factors K t s to the depths h and diameters È of blind holes were investigated based on the finite element method. The E-Mode, built-in the lock-in thermographic technique, was used to determine the stress distribution around blind holes and to predict the variation of K t s. Good predictions were achieved between the thermography and finite element method. The Altair Li software and Altair software were, separately, used to study the variations of the intrinsic dissipation and temperature increment during fatigue process for the purpose of damage status analysis. These two signals were considered as fatigue damage markers to rapidly predict the fatigue limits of components with different blind holes and then to determine the fatigue notch coefficient K f . Theoretical results validate the capability of the lock-in thermography for fatigue evaluation.
