Influence of Groove Angle in V-groove Butt joints on Transverse shrinkage in CO2 Arc Welding process

Welding induces transverse shrinkages in welded structures that results in reduced strength of welded joints in manufacturing industries. The analysis of transverse shrinkages is important in point of view of performance of welded joints. In view of this of experimental analysis of transverse shrinkage in single and double V-groove butt welded joints by varying groove angle and keeping heat input constant in CO2 Arc Welding process. It is observed that, the maximum transverse shrinkage increases with increase in the included angle.
