Welding and Distortion Control

Welding and Distortion Control illustrates various welding methods with particular focus on shipbuilding, namely Sheet Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Submerged Arc Welding (SAW) and Electro-slag along-with single side and multi-electrode welding techniques. 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 have been explained to help welding engineers and structural designers to implement effective distortion control measures and to make production friendly designs for achieving the goal of near zero distortion in fabricated structures which will eliminate to a great extent the tedious post weld fairing work.
