Tube flaring process involves a conical tool of a certain length which is displaced to get an end flared tube, which is utilized to form a tight seal between pipes or tubes. Tube flaring refers to a kind of forging which is often a cold working operation. The tube forming process is widely used in several industries to form condenser pipes, car seat structures, exhaust piping, etc. Thin-walled tubes were used in automobiles to reduce the total weight for better performance. A conical tool is used for tube end forming in which the tool is moved into the tube known as conventional tube flaring. In this work, a numerical study was directed using FEA software ANSYS/Implicit which is used to analyze the stress conditions involved in tube flaring. Here, the tool is considered rigid and displaced by using displacement control by 25 mm, and other parameters were studied at this displacement. Effects of different semi-cone angles were also considered for the study.
