“…Ultrasonic immersion C-scan system provides a planar colour images of the object containing the information about defects and flaws. The C-scan images obtained from immersion scanning not only reveal the internal condition of the materials, but it can also reveal the type and location of flaws present in the sample and its operation is commonly based on pulse echo technique [12][13][14][15][16][17][18]. In this technique, the ultrasonic transducer is excited using the pulser/receiver, and signal is transmitted and received by the same transducer.…”

Ultrasonic non-destructive testing (NDT) is one of the prominent field involving inspection to evaluate defects, cracks, deposition or fusion of welding materials and dimensional measurements of the test piece(s). Ultrasonic immersion scanning systems are useful for various industrial and metrological applications. The conventional immersion system uses a dedicated pulser receiver module for the excitation and detection of signal from transducer and a fast analog data acquisition card (DAQ) to acquire the raw data into computer. Rigorous digital signal processing and filtering is used to extract desired information from the raw data. In the present work, development of an ultrasonic immersion C-scan testing system, intended for industrial and metrological applications, is described. The developed system uses a commercial ultrasonic flaw detector (UFD) for the data acquisition rather than using pulser receiver and DAQ card to acquire ultrasonic information. The software for the same has been developed in Visual Basic .NET framework to control all five servo motor based axes of the ultrasonic immersion scanning tank. The developed software scans the sample automatically with parameters specified by the user. The parameters include echo amplitude, echo location, separation between two echoes, and ultrasonic attenuation. The developed software generates the data files that can later be used for further analysis using suitable data analysis software such as Origin or MS excel. The functionality of the developed system has been tested for the detection of flaws present in the material, testing for thickness variation and ultrasonic attenuation. The developed system is capable of detecting the location of defects within the resolution of ±0.01 mm. Ultrasonic transducer movement resolution of ±0.01 mm over the sample, results in to generation of a high quality image.

“…Large amounts of end-of-life products scrapped directly have led to excessive waste of resources over recent years, which can be significantly improved by remanufacturing [1][2][3]. Remanufacturing is an industrial process whereby used products can be restored to useful life [4], including design [5], disassembly [6], cleaning [7], inspection [8], reconditioning [9], etc., among which cleaning is a particularly essential procedure because the cleanliness of cleaned substrate has a significant influence on the following procedures. The ideal state of remanufacturing cleaning is to remove all the contaminants on the surface without affecting the substrate [10].…”

As an environmentally friendly method, water jet (WJ) technology plays a significant role in the field of remanufacturing cleaning. The cleaning capacity of a WJ is severely restricted by the water pressure, while the impact force will be too large and may damage the cleaned substrate as well as cause energy waste if the pressure is too high. However, by adding abrasives, the cleaning capacity of a low-pressure water jet (LPWJ) will be considerably improved. Although abrasive water jet (AWJ) technology has been used in mechanical machining for decades, very limited research work can be found in the literature for remanufacturing cleaning. In this paper, the role of abrasives in low-pressure abrasive water jet (LPAWJ) cleaning was described. Cleaning performance with different parameters (abrasive feed rate condition, water pressure and standoff distance) in paint removal was experimentally investigated by using the Taguchi design of experiment. The experimental results indicated that the water pressure was the most dominant factor and the optimal parameter combination was the second feed rate condition, 9 MPa water pressure and 300 mm standoff distance. The influence law between the cleaning performance and various factors was explored, which can provide remanufacturers with directions in selection of the optimal parameters in the LPAWJ cleaning process. By designing contrast experiments, the results showed that the cleaning capacity of an LPAWJ is better than that of a pure LPWJ and the residual effect in terms of changes in surface roughness, residual stress and morphology is a little larger.

More and more attention is being paid to non-destructive testing of connecting elements. Currently, ultrasound control is widely used. A prerequisite for an effective and reliable process of ultrasonic testing is the grain size of the analysed metal. One option for influencing non-grain size of a steel part is to vary the heat treatment and tempering conditions. As part of the study, an assessment was made of the heat treatment modes of steel parts for grain size. It has been established that by changing the heat treatment and tempering regime it is possible to obtain grain with a size of 3-5 points. The optimal mode of the heat treatment process was selected, which allows to obtain the minimum grain size of 4-5 balls that is acceptable for ultrasonic testing.
