  • welding Metallurgy of stainless steels during resistance spot welding part ii heat affected zone and Mechanical performance
    Science and Technology of Welding and Joining, 2015
    Co-Authors: M Alizadehsh, Majid Pouranvari, S P H Marashi
    Abstract:

    AbstractImplementation of new materials in automotive body-in-white requires through knowledge of their metallurgical response to welding process thermal cycle. This two-part paper aims at understanding the physical and Mechanical Metallurgy of stainless steels, as interesting candidates for automotive application, during resistance spot welding. The second part addresses the phase transformations in the heat affected zone of three types of stainless steels including austenitic, ferritic and duplex steels. Failure modes and Mechanical properties of stainless steel resistance spot welds are discussed. The peak load and energy absorption of stainless steel resistance spot welds are compared with advanced high strength steels.

  • critical review of automotive steels spot welding process structure and properties
    Science and Technology of Welding and Joining, 2013
    Co-Authors: Majid Pouranvari, S P H Marashi
    Abstract:

    AbstractSpot welding, particularly resistance spot welding (RSW), is a critical joining process in automotive industry. The development of advanced high strength steels for applications in automotive industry is accompanied with a challenge to better understand the physical and Mechanical Metallurgy of these materials during RSW. The present paper critically reviews the fundamental understanding of structure–properties relationship in automotive steels resistance spot welds. The focus is on the metallurgical characteristics, hardness–microstructure correlation, interfacial to pullout failure mode transition and Mechanical performance of steel resistance spot welds under quasi-static, fatigue and impact loading conditions. A brief review of friction stir spot welding, as an alternative to RSW, is also included.
