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 platesProvides computational tools that can give
insight into the effects of welding and fabrication
proceduresDemonstrates how welding distortion in thin plate
fabrications can be minimized through design
