Predictive Formulae for Weld Distortion available in PDF, EPUB and Kindle. &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.

Control of Welding Distortion in Thin-Plate Fabrication available in PDF, EPUB and Kindle. 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

[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.
