PREDICTION OF SURFACE RESIDUAL STRESSES IN BUTT-WELDED STEEL PLATES BY MAGNETIC BARKHAUSEN NOISE ANALYSIS

2010-06-11
Residual stresses have significant inflences on the service performance of the welded components. Various studies have been continuing to develop nondestructive methods for determination of residual stresses with portable equipment and short measurement time, as an alternative to the existing techniques such as X-ray diffraction. This study aims to investigate the applicability of Magnetic Barkhausen Noise method on predicting surface residual stresses in the welded steel plates.

Review of Residual Stress Measurement by Magnetic Barkhausen Noise Technique
Gür, Cemil Hakan (2018-01-01)
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 interac...

Hızlı, Hüseyin; Kaleli, Tuğçe; Gür, Cemil Hakan (null; 2016-10-01)
Residual stress state on the surface layers has a critical effect on the service performance and fatigue life of the carburized components. Non-destructive determination of residual stress state in a rapid and reliable way has being gained importance for industrial applications. The aim of this study is to investigate the efficiency of the magnetic Barkhausen noise (MBN) method for monitoring the residual stress variations as a function of carburizing process parameters. For this purpose, MBN and XRD measur...

Yelbay, Hasan İlker; Çam, İbrahim; Gür, Cemil Hakan (2010-01-01)
The purpose of this study is non-destructive determination of residual stresses in the welded steel plates by Magnetic Barkhausen Noise (MBN) technique. A MBN-stress calibration set-up and a residual stress measurement system with scanning ability were developed. To control the accuracy and the effectiveness of the developed system and procedure, various MBN measurements were carried out. The MBN results were verified by the hole-drilling method. Microstructural investigation and hardness measurements were ...
Investigating the Effects of Subsequent Weld Passes on Surface Residual Stresses in Steel Weldments by Magnetic Barkhausen Noise Technique
Gür, Cemil Hakan; Batıgün, Caner; Çam, İbrahim (2016-03-01)
Variations of surface residual stresses with subsequent weld passes were investigated in API 5L X70 steel plates by the magnetic barkhausen noise (MBN) technique. The plates were welded by applying a number of different passes under fully clamped conditions. After each weld pass, the MBN signal and hardness distributions on the front and back surfaces of the plates were measured. A specific calibration procedure and setup were used for conversion of the MBN signals into elastic stress values. The results we...
Monitoring variation of surface residual stresses in shot peened steel components by the magnetic Barkhausen noise method
SAVAŞ, SERDAR; Gür, Cemil Hakan (2010-12-01)
Shot peening is a cold working process by which residual compressive stresses are induced in the surface and near-surface region to increase the fatigue strength and the resistance to stress corrosion cracking This study covers non-destructive evaluation of surface residual stresses in the shot peened steel components by the magnetic Barkhausen noise method For this purpose various sets of steel specimens were prepared by a controlled shot peening process with different intensities impact angles and coverag...
