INVESTIGATION ON INERTIA FRICTION WELDING ANALYSIS PROCESS ON TI-CU MATERIAL THROUGH LINEAR CONDITION

Abstract

Friction welding's basic principle was intermetallic bonding at the point of superplasticity achieved with self-generating heat due to finished upset strain and friction. Different metal connections are now particularly common in the fields of defense, aerospace, automotive, biomedical, refining, and nuclear engineering. Because of their low bonding strength, some special alloys with dual phases cannot be successfully joined by friction welding. The metallurgical transformations in an interfacing line on the alloy surfaces after bonding are also visible. Research is scarce in this field that has been published. Although several trials were conducted to obtain a Region of sound weld in an uninterrupted connection between Tie6Ale4V and SS304L, the joint is not effective. The friction welding properties of Tie6Ale4V and SS304L with pure OFC as an overlay were analyzed in this paper. To reduce the number of experiments required, the BoxeBehnken design was used. The automatic strength of the weld joint was investigated. The highest tensile strength was obtained between Tie6Ale4V and SS304L, where pure Cr was used as the insert metal. EDS was used to perform structural and microstructural investigations. XRD analysis was used to identify the formation of a metal matrix at the interface.
