FWTPET Investigation on SA213 Tube to SA387 Tube Plate

In this research work, an experimental investigation of Friction Welding of Tube to Tube Plate with External Tool (FWTPET) has been carried out using backing block arrangement with interference fit. The Materials have been used in this research of SA213 tube and SA387 tube plate. The results of the experimental investigation revealed that by employing backing block, FWTPET is capable of producing defect free welds. The Welding sample has been conducted several characteristics such as Compression test, radiographic test and Microscopic Test. Further Taguchi L9 orthogonal array was utilized to find the most significant control factors which will yield better joint strength. Besides, the contribution of each process parameter has been determined using statistical analysis of variance (ANOVA). The Input and Output values are 1320 rpm Speed, 0 mm projection, 0.1 mm Depth of cut and 3086.90 MPa optimal joint strength respectively.
