A Study on Friction Stir Welding with Heating of Aluminum Alloy


Article Preview

Conventional Friction Stir Welding (FSW) is that weld materials are joint at room temperature by stirring softened materials due to frictional heat of rotating tool. Therefore, high speed and high efficiency would be expected, as pre-heating make weld materials more softened, as well known that yield point goes lower due to heating. In this study, FSW was done to improve welding speed on FSW of aluminum alloy (A5052) for high vacuum vessel for processing of electronics devices. As the result, welding speed was 2.0 times to more than 3.0 at 300 oC comparing with conventional FSW at room temperature, using improved a milling machine with heater.
