This book thoroughly covers the practical aspects of aluminum welding and the necessary process controls to achieve quality and class-approved welds. The inherent thermophysical properties of aluminum complicates welding, and this book addresses the practical aspects of aluminum welding based on the authorAs teaching and project experience in marine and ship construction technology. Features include: Descriptions of properties, applications, and designations of wrought and cast alloys. Various types of power sources and their effect in aluminum welding. Weld metal transfer mechanism and its dependence on process variables. General problems encountered in gas tungsten welding of aluminum alloys . Detailed treatment of distortion mechanisms types and causes. Numerical methods for analyzing thermal distortion and residual stress.
