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 were analyzed by considering microstructure investigations and hardness measurements, and then the results were compared with the results of X-ray diffraction measurements. MBN measurement after appropriate calibration seems to be a good candidate for rapid nondestructive monitoring of the variation of surface residual stresses in welded components. Moreover, it might provide critical data for computer simulation and weld process design, leading to a higher performance and longer life in service by controlling the residual stress state.

Investigating the effect of number of weld passes on the residual stress state of steel plates by micro magnetic method Erian, Gökhan; Batıgün, Caner; Çam, İbrahim; Gür, Cemil Hakan (null; 2012-09-17) Variations of surface residual stresses with subsequent weld passes were investigated in the API 5L X70 steel plates by Magnetic Barkhausen Noise (MBN) method. The plates were welded by applying different number of passes under fully clamped condition. After each weld pass, MBN signal and hardness distributions on the front and back surfaces of the plates were measured.

NONDESTRUCTIVE MONITORING OF VARIATIONS OF RESIDUAL STRESSES IN STEEL WELDMENTS BY MAGNETIC BARKHAUSEN NOISE METHOD Gür, Cemil Hakan; Batıgün, Caner; Çam, İbrahim (2013-07-18) Variations of surface residual stresses as a function of weld runs in API 5L X70 steel plates were non-destructively monitored by Magnetic Barkhausen Noise (MBN) method. After each weld run, MBN signal and hardness distributions were recorded. MBN signals were converted into stress values by using a specific calibration procedure. The results were analyzed by considering microstructure investigations and hardness measurements, and then, they were compared with the results of X-ray diffraction measurements. ...
Investigation of the variations in microstructure and mechanical properties of dual-matrix ductile iron by Magnetic Barkhausen Noise analysis Gür, Cemil Hakan; Erdogan, Mehmet (Informa UK Limited, 2008-01-01) The variations in the microstructure and tensile properties of dual-matrix ductile irons have been investigated non-destructively by Magnetic Barkhausen Noise (MBN) method. Specimens have been intercritically austenitised at 795 degrees C and 815 degrees C for 20 minutes, and then oil-quenched to obtain different martensite volume fractions. Two specimens, namely as-cast and oil-quenched from 900 degrees C, were prepared for comparison purpose. To investigate the effect of tempering, some specimens were tem...
