Recent developments in steel friction stir welding

has been established that friction stir welding of steel produces high integrity joints that exhibit excellent fatigue properties.From a simulation perspective,a local microstructural numerical model has been developed to predict the microstructural evolution within the weld zone during friction stir welding of low alloy steel.Segregation of Mn,Si,Al,and Oxygen During the Friction This work investigates the role of welding speed in elemental segregation of Mn,Si,Al,and oxygen during friction stir welding (FSW) in DH36 steel.The experimental work undertaken showed that when the speed of the FSW process exceeds 500 RPM with a traverse speed of 400 mm/min,then elemental segregation of Mn,Si,Al,and O occurred.Some results are removed in response to a notice of local law requirement.For more information,please see here.
