Abstract

Present research work deals with the selection of appropriate range of welding parameters and procedure that is used for conventional and narrow groove welding of thick sections at different welding process.The development of narrow gap welding procedure by P-GMAW process is carried out for joining of thick sections by appropriate reduction in number of weld passes and amount of weld metal. Study of the effect of variation in groove design and welding processes was performed by summarizing the mechanical properties of transverse shrinkage, tensile strength, and residual stress of weld joint.
