Friction Stir Welding of Steels presents the use of the FSW process on thick sectioned Ferritic-Martensitic steels whose success is credited for the use of advanced tool designs, tool materials, proper choice of heat input parameters, traverse speeds, and in-line monitoring of temperature rise at the tool/sample interface. The book covers all these unique aspects pertaining to FSW for different classes steels and their applications, including high strength Bainitic steels for automotive applications, maraging steels for space and missile applications, the variation in microstructure and mechanical properties, austenitic stainless steels, and chemical plants (pipe steels).

• Discusses problems associated with joining of steels using traditional fusion welding techniques, proposing FSW as an alternative
• Reviews the criteria for selection of tool material(s)
• Previews the optimization of process parameters, including technical recommendations
