Load Bearing Capacity of Tool Pin during Friction Stir Welding

Although friction stir welding (FSW) is now widely used for the welding of aluminum and other soft alloys, premature tool failure limits its application to hard alloys such as steels and titanium alloys. The tool pin, the weakest component of the …

Cooling rate in the 800°C to 500°C range from dimensional analysis

Structure and properties of steel welds are affected by their cooling rates in the 800 to 500°C range. The available cooling rate correlations are based mostly on heat conduction equation that ignores convective heat transfer and are inaccurate or …
