“…In recent studies, MBN data has been compared with X-ray diffraction and hole drilling method [15,16]. In these experiments, the hole drilling method was performed with a hole with 2 mm of depth, but with extensometer placed at the surface [15,16]. Thus, some variation of presented results [15,16] should be due to the fact that these different techniques (MBN, X-ray diffraction, and hole drilling) assess stress at different depths.…”

Interpretation of Magnetic Barkhausen Noise Bursts in Low Frequency Measurements

Experimental results allow the identification of three main magnetic Barkhausen noise bursts, each occurring at a different applied field. Magnetostrictive effects can be related to the 1st and 3rd bursts, because closure domain walls are created and/or eliminated. The 2nd burst occurs at the coercive field and it is usually the most intense, and is attributed to domain wall movement. The analysis of the three main bursts gives an important insight on how stress may affect the losses and magnetic Barkhausen noise. A brief review is also presented about the magnetic Barkhausen noise technique.

“…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].…”

Evaluation of Welding Distortion and Hardness in the A36 Steel Plate Joints Using Different Cooling Media

et al. 2022

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.

Determination of residual stress state is important for quality, integrity, and service performance of the components and structures. Almost all manufacturing processes cause considerable amounts of residual stress; thus, any process or product design ignoring it involves a risk for distortion or early failure. Among the existing methods, the magnetic Barkhausen noise method has been gaining attention for measuring residual stresses nondestructively in ferromagnetic materials. It is sensitive to the interactions between the magnetic structure and microstructure or residual stress fields. So far, successful qualitative results have been obtained for monitoring the residual stress variations on the surfaces of the components manufactured by various processes. However, some challenging tasks exist, such as obtaining reliable quantitative results when residual stresses and microstructure change at the same time or extracting depth-specific information. This article reviews the studies for the measurement of residual stress by magnetic Barkhausen noise method, particularly focusing on the processes widely used in industry, namely shot peening and welding.
