The joining aluminum and steel is encumbered by a range of metallurgical challenges including coefficient of thermal expansion and melting point differences, as well as the formation of deleterious intermetallics. Friction welding has demonstrated the capability to mitigate many of these challenges. When properly managed, friction welding facilitates control of temperatures and times in the joint, minimizing intermetallic formation and loss of properties.
EWI Technology Leader Jerry Gould has written Candidate Friction Welding Methods for Joining Aluminum to Steel to address these issues and describe candidate friction methods that have proven successful for aluminum to steel joining. To read the complete article, click here.
