Welding and Distortion Control reviews key welding methods, including sheet metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), submerged arc welding (SAW), and electroslag welding (ESW). Single-side and multi-electrode welding techniques are discussed. A special emphasis is placed on welding in shipbuilding and other heavy fabrication industries. Heat flow analysis and mechanical response using a constant stiffness system are described. Coverage is also provided of distortion prediction tools for large stiffened panels. The chapter on welding distortion starts by explaining the distortion mechanism and subsequently introduces various types of distortions encountered and their prediction methods. Suitable distortion prediction tools are explained to help welding engineers and structural designers implement effective distortion control measures. Information is provided on production-friendly designs for achieving the goal of near zero distortion in fabricated structures to reduce or eliminate the need for tedious postweld fairing work
