Optimization of Friction Welding of Tube-to-Tube Plate Using an External Tool with Filler Plate

摘要

Friction welding of tube-to-tube plate using an external tool (FWTPET) process with filler plate was successfully applied and optimized for joining commercially pure aluminum tube and tube plate. Taguchi approach was applied to determine the most influential control factors which will yield better joint strength. L_9 orthogonal array was used in this study. Through the Taguchi parametric design approach, the optimum levels of process parameters were determined. The percentage of contribution of each process parameter was determined by Analysis of variance. The predicted optimal value of joint strength was found to be 83.26 MPa. The results were confirmed by further experiments.
