[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.

Finite Element Analysis of Weld Thermal Cycles Using ANSYS available in PDF, EPUB and Kindle. Finite Element Analysis of Weld Thermal Cycles Using ANSYS aims at educating a young researcher on the transient analysis of welding thermal cycles using ANSYS. It essentially deals with the methods of calculation of the arc heat in a welded component when the analysis is simplified into either a cross sectional analysis or an in-plane analysis. The book covers five different cases involving different welding processes, component geometry, size of the element and dissimilar material properties. A detailed step by step calculation is presented followed by APDL program listing and output charts from ANSYS. Features: Provides useful background information on welding processes, thermal cycles and finite element method Presents calculation procedure for determining the arc heat input in a cross sectional analysis and an in-plane analysis Enables visualization of the arc heat in a FEM model for various positions of the arc Discusses analysis of advanced cases like dissimilar welding and circumferential welding Includes step by step procedure for running the analysis with typical input APDL program listing and output charts from ANSYS.

This book was released on 1979. Prediction and Control of Residual Stresses and Distortion in HY-130 Thick Pipe Weldments available in PDF, EPUB and Kindle. 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.

Minimization of Welding Distortion and Buckling available in PDF, EPUB and Kindle. Welding is a cost-effective and flexible method of fabricating large structures, but drawbacks such as residual stress, distortion and buckling must be overcome in order to optimize structural performance. Minimization of welding distortion and buckling provides a systematic overview of the methods of minimizing distortion and buckling in welded structures. Following an introductory chapter, part one focuses on understanding welding stress and distortion, with chapters on such topics as computational welding mechanics, modelling the effect of phase transformations on welding stress and distortion and using computationally efficient reduced-solution methods to understand welding distortion. Part two covers different methods of minimizing welding distortion. Chapters discuss methods such as differential heating for minimizing distortion in welded stiffeners, dynamic thermal tensioning, reverse-side heating and ways of minimizing buckling such as weld cooling and hybrid laser arc welding. With its distinguished editor and international team of contributors, Minimization of welding distortion and buckling is an essential reference for all welders and engineers involved in fabrication of metal end-products, as well as those in industry and academia with a research interest in the area.
