| Popis: | Ever since the Bronze Age, permanent fastening of materials has always been considered a good technique in the mechanical engineering field and it has now attained a gradual enhancement to get defect free joint. The continuous drive solid state rotary friction welding machine can make quality joint and emissions is almost nil. This study explores the possibility of using a solid-state welding process on EN 10028-P355 GH steel and AISI 430 Steel. In this research work, selected materials of 16 mm diameter rods are joined with help of friction welding to bring down Axial Shortening and improve Tensile Strength, Impact toughness of the joint. The selected materials find extensive applications in pump shafts, boilers, and pressure vessels. The frictional pressure, upset pressure, frictional time, upset time, and rotational speed are the input factors with three levels each that have been considered for this work. The experiment involves an L27 Orthogonal Array. The merits of a grey theory are combined with the statistical analyzing capabilities of response surface methodology in an integrated approach of grey incidence reinforced response surface methodology to select the optimal friction welding inputs. The optimal friction welding inputs were validated with proper experiments. The improvement of the properties attained for the dissimilar EN 10028 P355GH Steel & AISI 430 Steel joint is 1.93%, 5%, and 11.5% of maximum ultimate tensile strength, impact toughness, and axial shortening respectively. The study will offer the guiding database for welding steel in a solid state using continuous drive friction welding. |
