“…Another way is to look at their parallel paths and overlapping areas. The relationship between the industrial revolutions and the evolution of non-destructive testing is successfully described in the study by Liu et al [11] as a parallel course from manually applied NDT during Industry 1.0, to the use of instruments (Industry 2.0), to a digital, automated NDT (Industry 3.0) up until the current version of NDT which is not only digital and automated but also visualized. During this evolution the dependent degree of operator appears to be declining giving its place to the degree of intelligence.…”

The 4th Industrial Revolution (4IR) is developing, leading the transition to the post-industrial era. Both the industry and the business world as well as the civil society, have already realized that the world as it exists is about to change due to the 4th Industrial Revolution. Many countries and stakeholders, realizing (4IR)’s importance, have already incorporated it into official policies while the companies at the forefront are called upon to integrate a variety of new technologies. Among other technologies, in this context, the evolution of non-destructive testing is of significant importance, having a positive impact not only on productivity but also on numerous technical, managerial, and economical aspects of the final product. The present work attempts to highlight this issue and form the basis for relevant future research.

Tool frame calibration has been widely used in robot-assisted printing, welding, and grinding, but it is not suitable for ultrasonic testing because the robot is submerged in water. The purpose of this paper is to present a tool frame calibration method, which is suitable for improving the precision of ultrasonic testing. In uniform mediums, sound travels along a straight line like ray. A reflector is fixed in water to reflect ultrasound, which makes it possible to measure distances between incidence points on a reflector and tool center point (TCP) on an ultrasound transducer. In addition, the positions and poses of the end flange are recorded through a robot controller. Finally, an optimization method is applied to calculate the position and pose errors of the tool frame relative to the end flange according to such records. The presented method was implemented in an ultrasonic testing system. We selected 100 incidence points on the reflector to calculate the assembly errors of the transducer. The pulse amplitude rose obviously after calibration, which verifies that this is an effective method. Considering that ultrasonic transducers can be used as a measuring tool, this paper proposes a tool frame calibration method for ultrasonic testing robots without introducing other measuring devices, which draws the conclusion that tool frame can be calibrated through ultrasound.

Delamination in composite laminates reduces the structural stiffness and thus causes changes in the vibration responses of the laminates. Therefore, it is feasible to employ dynamic characteristics (such as natural frequencies and mode shapes) for delamination detection by using an optimization method. In the present study, a two-step method is proposed for the delamination detection in composite laminates using an experience-based learning algorithm. In the first step, one-dimensional equivalent through-thickness beam elements are employed to model the composite laminated beam and potential delamination locations are identified. In the second step, a typical three-dimensional finite mesh is utilized for the beam’s modeling and the detailed delamination information (including the delamination location, size, and interface layer) is detected. This two-step method combines the advantages of the two different modeling techniques and is able to significantly reduce the computational cost without reducing detection accuracy. The proposed method is applied for an eight-layer quasi-isotropic symmetric (0/-45/45/90)s composited beam with different delamination situations to verify its effectiveness and robustness. The performance of the two-step method is demonstrated by comparing with the one-step method and other three state-of-the-art algorithms (CMFOA, PSO, and SSA). Moreover, the influence of artificial noise on the accuracy of the detection performance is also investigated. Both numerical and experimental results confirm the superiority of the proposed method for delamination detection in composite laminates especially for the prediction of delamination interface.
