abstract = "Friction-stir-welding (FSW) is a solid-phase joining process, and many studies on the application to structural steels have been published. In this study, FSW of thick carbon steel was conducted using heat-resistant moldable Co-based alloy tools. In the weld trials, acceptable appearances were created using a tool with a probe shorter than 9 mm, while a tool with a 12-mm long probe could not successfully weld the materials. The stir zone (SZ) had slightly higher hardness than the base material and fine grains of less than 10 μm in diameter. Comparing the different tool geometries, the tool with 3-flats and a step spiral embedded in the probe effectively reduced the output power of the motor for tool rotation.",
