Title: Friction weld ductility and toughness as influenced by inclusion morphology

Abstract

Friction welding provides consistently high strength, freedom from fusion defects, and high productivity. However, friction welds in carbon steel exhibit impact toughness and bend ductility significantly lower than that of the parent metal. The inclusion content and morphology were suspected to be major contributors to this reduction in weld ductility. Four electric furnace steels, three types of ASTM A516 Grade 70 and ASTM A737 Grade B, were investigated. Friction welds were made by both the inertia and continuous drive processes and the welds evaluated. It was shown that friction welds of inclusion controlled steels exhibited much improved toughness and bend ductility.
