Self-Reacting Friction Stir Welding for Aluminum Alloy

Friction stir welding is an innovative weld process that continues to grow in use,in the commercial,defense,and space sectors.It produces high quality andSegregation 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.Recent Development in Friction Stir Welding Process AThe Friction stir welding (FSW) is recently presented so to join different materials without the melting process as a solid-state joining technique.A widely application for the FSW process is recently developed in automotive industries.To create the welded components by using the FSW,the plunged probe and shoulder as welding tools are used.

Proposed Hybrid Processes for Part Building Using Fusion
