This book was released on 1989 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was carried out with the specific intention of reducing the undesirable effects of both high residual stresses and distortion in HY100 and HY130 high strength steels during welding. Tests were also conducted on Mild Steel for comparison. The goal of these tests was to first ascertain the distortion and residual stresses during and after welding of test pieces of the three different steels. Test specimens were: 5.5' wide by 18' long and 0.5' thick. A nominal 20 KJ/inch heat input was used in all experiments. Bead on edge was utilized as representative of a butt weld. An automated GMA process was utilized for welding with 98% argon and 2% oxygen as shielding gas. (JES).

This book was released on 1979 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to validate existing techniques for computer simulation of the welding process, an experiment is designed and carried out in which seam and girth welds are produced on a high strength steel cylinder. Fabrication of the HY-130 cylinder, selection of welding parameters for the seam and girth welds, and the selection and arrangement of instrumentation are described. The theoretical background of finite element computer simulation of heat flow in weldments as well as techniques for axisymmetric finite element analysis of thermal stress and metal movement during welding are discussed. Finite element representation of weldment geometry for heat flow and stress analysis is presented. Metallurgical properties of the HY-130 cylinder seam weld are presented in the form of photo-micrographs and electron scan micrographs. Temperature, strain, and radial distortion are measured at various locations on the HY-130 cylinder and the measured values are compared.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Examines the factors that contribute to overall steel deformation problems. The 27 articles address the effect of materials and processing, the measurement and prediction of residual stress and distortion, and residual stress formation in the shaping of materials, during hardening processes, and during manufacturing processes. Some of the topics are the stability and relaxation behavior of macro and micro residual stresses, stress determination in coatings, the effects of process equipment design, the application of metallo- thermo-mechanic to quenching, inducing compressive stresses through controlled shot peening, and the origin and assessment of residual stresses during welding and brazing.

Download or read book Processes and mechanisms of welding residual stress and distortion written by Zhili Feng and published by CRC Press. This book was released on 2005-11-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a fabrication technology, welding presents a number of technical challenges to the designer, manufacturer, and end-user of the welded structures. Both weld residual stress and distortion can significantly impair the performance and reliability of the welded structures. They must be properly dealt with during design, fabrication, and in-service use of the welded structures. There have been many significant and exciting developments on the subject in the past ten to fifteen years. Measurement techniques have been improved significantly. More importantly, the development of computational welding mechanics methods has been phenomenal. The progresses in the last decade or so have not only greatly expanded our fundamental understanding of the processes and mechanisms of residual stress and distortion during welding, but also have provided powerful tools to quantitatively determine the detailed residual stress and distortion information for a given welded structure. New techniques for effective residual stress and distortion mitigations and controls have also been applied in different industry sectors. Processes and Mechanisms of Welding Residual Stress and Distortion provides a comprehensive summary on the developments in the subject. It outlines theoretical treatments on heat transfer, solid mechanics and materials behavior that are essential for understanding and determining the welding residual stress and distortion. The approaches for computational methods and analysis methodology are described so that non specialists can follow them. There are chapters devoted to the discussion of various techniques for control and mitigation of residual stress and distortion, and residual stress and distortion results for various typical welded structures are provided. The second half of the book looks at case studies and practical solutions and provides insights into the techniques, challenges, limitations and future trends of each application. This book will not only be useful for advanced analysis of the subject, but also provide sufficient examples and practical solutions for welding engineers. With a panel of leading experts this authoritative book will be a valuable resource for welding engineers and designers as well as academics working in the fields of structural and mechanical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: &Quot;The quantification of the level of distortion that can be expected after welding has become crucial to meet the increasingly stringent accuracy requirements for the design of any type of fabricated component or structure. Many research workers have formulated weld distortion prediction models in order to reduce the extent of practical trials required to determine actual distortion. Because of the large number of prediction models available, some guidance is required on the selection of appropriate models for a particular welding application. For this reason, this review of published weld prediction formulae has been carried out within the Core Research Programme of TWI. Whilst reviews have been carried out in the past, this summary differs in that it covers four types of distortion - longitudinal shrinkage, bowing distortion, transverse shrinkage and angular distortion. It provides a critical assessment of each of the models; highlighting where background information exists, whether the model has been validated and possible limitations. Based on the information available for each of the models and on TWI's knowledge and experience, one or more models are recommended for each type of distortion."--BOOK JACKET.
