Submerged Arc Welding is an important industrial joining process used extensively for welding of thick plates. Hence, finds utility in heavy fabrication industries like ship building and pressure vessel industry. The process is characterized as a high heat input process which sometimes leads to certain weld abnormalities of which angular distortion is the one. The present work is an attempt to analyse the effect of input welding parameters like Wire Feed Rate, Voltage and Welding Speed on angular distortion which is a response parameter. Angular Distortion is caused because of the non uniform thermal stresses experienced by the top and bottom surfaces of the weld with top surface getting the maximum and the bottom surface getting the minimum thermal effects. This causes top surface to experience more contraction as compared to bottom resulting in distortion of weld across the line of weld known as angular distortion. This distortion may result in rejection, scrap or misfit of the weldment with parent structure. It is therefore important to keep this defect to a minimum and the present study is an attempt to work in this direction. The results are expected to be of practical importance from the industrial viewpoint.
