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.

Available in PDF, EPUB and Kindle. Book excerpt: The intense temperature fields caused by heat sources in welding frequently lead to distortions and residual stresses in the finished product. Welding distortion is a particular problem in fabricating thin plate structures such as ships. Based on pioneering research by the authors, Control of Welding Distortion in Thin-Plate Fabrication reviews distortion test results from trials and shows how outcomes can be modeled computationally. The book provides readers with an understanding of distortion influences and the means to develop distortion-reducing strategies. The book is structured as an integrated treatment. It opens by reviewing the development of computational welding mechanics approaches to distortion. Following chapters describe the industrial context of stiffened plate fabrication and further chapters provide overviews of distortion mechanics and the modeling approach. A chapter on full-scale welding trials is followed by three chapters that develop modeling strategies through thermal process and thermo-mechanical simulations, based on finite-element analysis. Simplified models are a particular feature of these chapters. A final sequence of chapters explores the simulation of welding distortion in butt welding of thin plates and fillet welding of stiffened plate structures, and shows how these models can be used to optimize design and fabrication methods to control distortion. Control of Welding Distortion in Thin-Plate Fabrication is a comprehensive resource for metal fabricators, engineering companies, welders and welding companies, and practicing engineers and academics with an interest in welding mechanics. Allows practitioners in the field to minimize distortion during the welding of thin plates Provides computational tools that can give insight into the effects of welding and fabrication procedures Demonstrates how welding distortion in thin plate fabrications can be minimized through design

Book excerpt: [Author's abstract] Deformations and stresses induced in plates due to high temperatures represent a major concern in various structural applications. The stringent requirement of designs and to have lower production costs, these deformations needs to be addressed. In welding process, one approach used to minimize deformation is to provide sufficient clamps where the warping will be expected to occur. This takes lot of experience to know where the required tooling is to be applied and thus increases the overall cost. Avoiding clamping during the welding process would result in obvious deformations necessitating modification of the assembly process and increasing the manufacturing time. Therefore, many industries have concluded that there is a strong need for some technique that would predict the places where the sheet metal distortion would occur and reduce or eliminate the need for redundant tooling. The purpose of this study is to examine the feasibility of predicting the location and range of deformations due high temperature differences occurring during welding process. This is done, in part, to try to do effective tool design for clamping purpose. The study was performed using PRO/Mechanica package. The actual deformations occurring on the plate were measured manually to validate the simulation. As the results show, the suggested method of analysis can be used to a considerable degree of accuracy.

Book excerpt: Welding and Distortion Control illustrates various welding methods with particular focus on shipbuilding, namely Sheet Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Submerged Arc Welding (SAW) and Electro-slag along with single side and multi-electrode welding techniques. The chapter on welding distortion starts by explaining the distortion mechanism and subsequently introduces various types of distortions encountered and their prediction methods. Suitable distortion prediction tools have been explained to help welding engineers and structural designers to implement effective distortion control measures and to make production friendly designs for achieving the goal of near zero distortion in fabricated structures which will eliminate to a great extent the tedious post weld fairing work.

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.
