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. MBN method seems to be a good candidate for monitoring the variation of surface residual stresses. It may also provide critical data for computer simulation and process design of welding processes.

Beam Switching Reflectarray with MEMS Controls Bayraktar, Omer; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2010-04-16) This paper presents a 26.5 GHz beam switching reflectarray monolithically fabricated on glass substrate with the RF MEMS switches. The array is formed using 10x10 aperture coupled microstrip patch antenna (ACMPA) elements. RF MEMS switches are implemented on the transmission lines in order to sustain the beam switching. A prototype of a reflectarray with 90 RF MEMS switches is monolithically produced using an in-house surface micromachining process including the wafer bonding steps. The measurement result s...
Inertial parameter design of spatial mechanisms Can, Fatih Cemal; Soylu, Reşit; Department of Mechanical Engineering (2003) In this thesis, the inertial parameters of a spatial mechanism are used in order to optimize various aspects of the dynamic behaviour of the mechanism (such as minimizing actuator torque/ force fluctuations, shaking force/moment balancing, etc.) while the effects of loads are considered as well. Here, inertial parameters refer to the mass, 6 elements of the inertia tensor and coordinates of the center of mass of the links. The concept of Force Fluctuation Number (FFN) is utilized to optimize the dynamic beh...
Non-destructive determination of residual stress state in steel weldments by Magnetic Barkhausen Noise technique 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 ...
Non-destructive evaluation of residual stresses in the multi-pass steel weldments Erian, Gökhan; Gür, Cemil Hakan; Batıgün, Caner; Department of Metallurgical and Materials Engineering (2012) The purpose of this thesis is non-destructive determination of residual stress state in the multi-pass welded steel plates by Magnetic Barkhausen Noise (MBN) technique. To control the effectiveness of the developed procedure, continuous MBN measurements on the heat affected zone and parent metal of the welded plates were performed. In the experimental part, various steel plates were welded with different number of weld passes. Various series of samples were prepared for residual stress and for angular defle...
Production system optimization for submersible pump lifted wells : a case study Güler, Nuri Ozan; Bağı, A. Suat; Department of Petroleum and Natural Gas Engineering (2004) A computer program has been written to perform production optimization in submersible pump lifted wells.Production optimization was achieved by the principles of Nodal Analysis Technique which was applied between the reservoir and the wellhead ignoring the surface choke and separator.computer program has been written according to two lifting environment,which are:pumping with only liquid,pumping with both liquid and gas.
