    • AbstractIntroductionKey IssuesMaterial WeldabilityHardenability and Fracture ModeOver the past 20 years, there has been a substantial effort to reduce vehicle body weight by the use of high strength, and more recently ultra-high strength steels, with tensile strengths up to 1500N/mm 2. Some of these materials present challenges to resistance spot welding, still the primary joining process for sheet steels. This paper covers the main issues of resistance spot welding these materials, including weldability, hardenability and joint properties. The changes in welding procedures needed to weld the High Performance Steel For Highway BridgesHigh carbon content of current conventional steels, needed to achieve high strength, leads to cracking during construction or while in service. To reduce cracking problems from welding, required for conventional steel, during welding. One of the goals in developing high performance steel is to reduce or eliminate preheat. This
