As welding is a heat induced process, weldment has to undergo thermal cycles during the process. Localized heating in welding, results in non-uniform heating and cooling of the weldment. Due to this non-uniform expansion and contraction, residual stresses are developed in the weldment. This results in undesirable distortion. It negatively affect the quality of welded structure. So, now a days industries are eager to implement advanced welding processes as a remedy of this distortion. Various advanced welding processes and methods are reviewed in this paper on the target of distortion reduction. The processes mainly involved Cold Metal Transfer (CMT), Autogenous laser welding, Hybrid laser-GMA welding, Hybrid laser-magnetic welding and effects of welding process conditions on distortion. Various Comparative study among different welding processes as a response of distortion are reviewed. This paper will give brief outline on distortion and effects of process conditions on distortion.
