Estimating the mechanical properties of friction welded AISI410 MSS joints using empirical relationship

The present study aims to develop the numerical relationship to attain maximum tensile strength of the friction welded AISI410 MSS joints by using response surface methodology. The friction welding (FW) process parameters considered for optimization namely rotational speed, upset pressure, friction time, and upset time. The FW parameters of 31 sets have been used to manufacture the joints to attain the maximum strength. Moreover, the detail relates the optimization procedure with respect to welding conditions on AISI410 MSS joints and its optimized parameters were reported. The optimized results have been correlated with the weld interface of the specimen with reference to tensile properties, macro and microstructure features, hardness, and fracture morphology. Finally, the results concluded that the rotational speed as the most effectual process parameter on the joint properties of the FW AISI410 MSS joint. (authors)
