Book excerpt: This cooperative research and development agreement (CRADA) between Concurrent Technologies Corporation (CTC) and Lockheed Martin Energy Systems (LMES) combines CTC's expertise in the welding area and that of LMES to develop computer models and simulation software for welding processes. This development is of significant impact to the industry, including materials producers and fabricators. The main thrust of the research effort was to develop a comprehensive welding simulation methodology. A substantial amount of work has been done by several researchers to numerically model several welding processes. The primary drawback of most of the existing models is the lack of sound linkages between the mechanistic aspects (e.g., heat transfer, fluid flow, and residual stress) and the metallurgical aspects (e.g., microstructure development and control). A comprehensive numerical model which can be used to elucidate the effect of welding parameters/conditions on the temperature distribution, weld pool shape and size, solidification behavior, and microstructure development, as well as stresses and distortion, does not exist. It was therefore imperative to develop a comprehensive model which would predict all of the above phenomena during welding. The CRADA built upon an already existing three-dimensional (3-D) welding simulation model which was developed by LMES which is capable of predicting weld pool shape and the temperature history in 3-d single-pass welds. However, the model does not account for multipass welds, microstructural evolution, distortion and residual stresses. Additionally, the model requires large resources of computing time, which limits its use for practical applications. To overcome this, CTC and LMES have developed through this CRADA the comprehensive welding simulation model described above.

Book Synopsis Processes and mechanisms of welding residual stress and distortion by : Zhili Feng
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.

Book Synopsis Understanding Weld Formation and Microstructure Evolution in Laser Welded Stainless Steels and Ti-6Al-4V by : Tate Patterson
Download or read book Understanding Weld Formation and Microstructure Evolution in Laser Welded Stainless Steels and Ti-6Al-4V written by Tate Patterson and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High energy density welding processes are used for many industrial applications, such as aerospace and defense, and certain joint configurations and welding situations render post-weld inspection techniques difficult. Due to the inability to confirm penetration, there is a continual industrial need to improve prediction capabilities to aid in parameter selection. It is also necessary to understand the microstructural evolution to modify phase fractions and mitigate weldability related concerns such as solidification cracking or reduced corrosion performance. Using an ytterbium doped fiber laser, partial penetration laser beam welds were produced on a six stainless steel (SS) alloys and Ti-6Al-4V. The WRC-1992 Cr/Ni equivalencies for the SS alloys ranged from 1.7 to 2.8. These alloys included a commercially available 304L stainless steel and a commercially available 2205 duplex stainless steel. The other four SS alloys were experimental compositions. From an industrial perspective regarding weld feature prediction, the two alloys of interest include 304L SS and Ti-6Al-4V. Therefore, analysis was performed to relate weld geometry characteristics to process parameters for these two alloys. The objective of the weld geometry analysis was to develop a neural network model that can predict weld geometry characteristics, most importantly penetration. The best results were produced with individual neural networks developed for each weld feature and compiled into a comprehensive algorithm. An inline coherent imaging (ICI) or depth measurement system was also incorporated during LBW to further understand keyhole evolution and weld pool development. Process parameters influenced the location of the keyhole relative to the process beam and the overall shape and width of the vapor capillary. Transverse and longitudinal view sections were evaluated to determine solidification behavior, and electron backscatter diffraction (EBSD) patterns were used extensively to determine phase fractions and grain size. For SS alloys, relationships among penetration mode (conduction vs. keyhole), composition (Creq/Nieq), and microstructure (solidification mode and phase fraction) are presented. The results presented provide a more complete picture of rapid solidification phenomena associated with laser welds in SS alloys over a wide range of compositions. For Ti-6Al-4V, the beta grain size and morphology were related to the welding conditions and weld pool shape. Prior-beta grains were reconstructed using EBSD analysis, and this information was used to determine the size, orientation, and growth of the beta grains at different travel speeds. Beta grain growth during solidification was strongly influenced by the weld pool shape and generally occurred by columnar growth from the fusion boundary to the weld surface and/or weld centerline. The average grain size decreased in the plan view orientation but showed minimal decrease in transverse and longitudinal sections.

Book Synopsis Welding: Theory and Practice by : D.L. Olson
Download or read book Welding: Theory and Practice written by D.L. Olson and published by Elsevier. This book was released on 2012-12-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gives a comprehensive and thorough review on recent advances in the science of welding and provides a treatise for their application in day-to-day welding activities. The essential science of welding is presented for the first time in a style that is comprehensible to the craftsman, engineer and scientist. The application of welding technology requires familiarity with a broad spectrum of engineering and science. The practitioners of this technology need to be familiar with mathematics, physics, chemistry, metallurgy, electrical engineering, and mechanical engineering to mention the basics. These practitioners may only have a scant knowledge in all areas, and this book is intended to provide those practising welding with a broad but subtly in-depth overview of the subject. To accomplish this the book is divided into: weld pool chemistry and microstructure, processes: high energy density; low energy density; and bonding, heat input and associated stress, and computer control. Each of these areas addresses the literature, the fundamental science and engineering, and where the technology stands with respect to the topic. The knowledge level anticipated is not that of a senior engineer or researcher, although they could enjoy the works as much as anyone, but is more designed for those involved in the daily practise of welding. Thus the book will be of interest to craftsmen, students, engineers, researchers, managers, and those interested in the Theory and Practice of welding.
