Unlike steel welding, aluminum welding is complicated because of its inherent thermo-physical properties. Hence to achieve quality - stringent process control is necessary. In this Second Edition four additional features have been incorporated and some existing chapters merged in an effort to make them more elaborate and rational. New to the Second Edition: · Details of gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) dealt with in separate chapters. · Heat flow analysis using finite difference scheme and simplified heat source model. · New chapter on friction stir welding (FSW). · FSW tool design and heat generation in friction stir welding. · Thermo-mechanically affected zone (TMAZ) and heat affected zone (HAZ) of friction stir welded joints explained. · Various properties of FSW joints, their corrosion and stress corrosion cracking resistance, defects and their detection discussed.
