Tube hydroforming is an emerging manufacturing technique that uses pressurized fluid to deform the metal tubes into the desired shape. It is carried out by keeping tubular blank in the die, then deforming it into the final shape by applying fluid pressure using axial punches. Components from TIG welded tubes of Austenitic stainless steels find automobile applications, particularly exhaust systems. But the effect of microstructure on the formability of tube is not focused much. Hence, in the present study, TIG weld tubes of AISI304 deformed and deformation behaviour is studied in comparison with bulge ratio and grain size effect. It was noticed that bulge height (deformation) decreased with increased bulge width and fracture surface observed with fine grain size & ductile nature.
