Review on distortion over welded structures

While welding started to be used on large scale in engineering, distortion has become a stringent problem for industry, mostly for shipyards. This paper aims to bring together the result of large amount of research on distortion and mitigation techniques, in order to support further practical research on topic. Phenomena was explained in detail, such as mostly used treatments for reducing distortion. In addition to this, inherent strain theory was presented for offering a starting point to those which shall perform thermal analysis in welded structures.
