The mechanical properties of a welded joint depend to a large extent on the geometry of the edge preparation. For the welding of thicker plates, edge preparation is necessary to ensure proper penetration, desired strength and to control weld distortions. The geometry of the edge preparation has an important consideration for the design and manufacturing of welded structures. Single-V groove type joint is most commonly employed for edge preparation, but for the plates having higher thickness (greater than 25 mm) this joint produces more angular distortions, residual stresses and less strength. For welding of thick plates, having thickness between 25 mm to 40 mm, Single-J joint is preferred. Geometric parameters of Single-J groove include groove angle, root gap and root face. The aim of this investigation is to investigate the effects of variations in geometric parameters of Single-J groove on mechanical properties and distortion characteristics of welded plates of stainless steel SS304 having thickness 25 mm. Welding was performed on TIG welding setup keeping all the other welding process parameters constant. The welded specimens were tested for tensile strength and bending test. Angular distortions in each welded specimen were also measured.
