Experimental Analysis of SA213 Tube to SA387 Tube Plate Welding by Using Close Fit Technique in Absence of Supporting Plate

摘要

Friction Welding Process was conducted by joining Seamless Austenitic 213 tube and Seamless Austenitic 387 tube plate alloying materials employing an external tungsten tool by close fit methods in the absence of backing plate without hole on the circumference of the tube for superior mechanical and metallurgical properties. The output parameter (TS) and input factors (rotation speed of the tool, tube projections, cutting depth) designated for this study. The grain size measurement, x-ray diffraction (XRD) phase analysis, radiography test is carried out after FWTPET process. In this research work, FWTPET process carried without hole on the circumference of the tube; further FWTPET process is also compared by without employing supporting arrangement. Excellent joint strength of 762.2 MPa is achieved with the absence of supporting specimen which without hole on the circumference of the tube for the tool rotational speed of 1300rpm.
