“…Experimental Platform Construction. In this experiment, a 5 mm thick standard Q235 steel tensile specimen was stretched using a universal tensile machine to simulate the steel structure's tensile strain under the actual working state [17][18][19]. The parametric diagram of this standard tensile specimen is shown in Figure 8.…”

To avoid strains in steel structures in special equipment caused by excessive alternating loads, which cause stress concentrations in local areas and reduce the strength and pressure-bearing capacity of the steel structures, a method for evaluating the strain state of the steel structures using the eddy current effect is proposed, and the relevant testing device is developed. The RMS voltage and tension values were tested and fitted linearly with sampling time, and their linear correlations after fitting were 0.9978560 and 0.9967905, respectively. To investigate the method’s practical application, the effect of strain on the impedance of the eddy current probe was first studied theoretically, followed by the design and fabrication of a strain detection device comprised of an eddy current probe and a signal processing system. Finally, tensile strain experiments were carried out on 5 mm thick standard Q235 steel tensile specimens using a universal tensile machine and the linear equation of RMS voltage versus strain was obtained analytically. Theoretical and experimental tests have shown that the device can detect each strain stage and quantify the strain within the elastic stage by fitting a linear equation.

“…The measurement of the residual stress on welded ASTM A36 steel plates through the MAG method has been examined using non-destructive techniques such as Magnetic Barkhausen Noise and X-ray Diffraction [28,29]. Moreover, process parameters such as the welding current and speed, arc voltage and distance, the laser-to-arc distance at the penetration depth, bead shape, arc stability, spark, and plasma formation have also been investigated in carbon steel [30].…”

The temperature difference in the weld area during the process of welding, cooling the welded product, and post-welding affect the formation of distortion. Therefore, this study aims to evaluate the distortion formed and hardness behavior on the ASTM A36 (EN S275) steel plate while welding using different cooling media including air, water, and ice. This involved using the MAG (Metal Active Gas) method, which used the AWS A5.18 ER70S-6 electrode with a 1 mm diameter and an 8 mm plate thickness. The value of distortion on the MAG-welded steel plate was measured using a digital dial indicator and evenly distributed by first making a grid. Moreover, the measuring points from the transverse and longitudinal directions were placed at 20 and 8 rows with a distance of 10 mm between points for each variation of the cooling media, such that 10 mm each was allowed left-right and top-down. The results showed that the highest distortion value of 3.13 was formed on the second row of the air cooling media, and this media was also used to determine the contours and distortion profiles.
