Welding Techniques, Distortion Control and Line Heating

Welding techniques and associated weld distortion problems encountered in heavy industries are very typical and need to be dealt with from a view point of their requirements. This book covers in detail aspects of welding, distortion control and line heating in the context of heavy fabrication, shipbuilding and offshore industry and includes different welding methods used namely SMAW, GMAW, GTAW, SAW, Electrogas, Electroslag and Friction Stir Welding.This book discusses in detail weld induced distortion mechanism, types of distortions, their estimation using finite element analysis, various distortion control mechanisms namely controlled heat input, structural fit-up, thermal tensioning and heat sinking, effect of welding sequence on fabrication of stiffened panels.
