The fusion welding methods have traditionally been, and are today, normally used in the manufacture of automotive structures. Recent augmented procedure of Advanced High Strength Steels (AHSS) in automotive designs posed a desire to evaluate the application of fusion welding processes relative to the joining of AHSS. New developments in advanced high strength steels (AHSS) have helped reduce weight, improve fuel efficiency, and increase the crashworthiness of vehicles through enhanced mechanical properties. This has accelerated the integration of AHSS into the automotive architecture and increased demands to understand the effects of RSW. As a result, there has been a recent focus on the weldability of these steels.Welding and Joining of Advanced High Strength Steels illustrates and reviews the range of welding and other joining technologies for Advanced High Strength Steel (AHSS) and how they can be best utilized to get the most of the potential of AHSS. It covers detailed methods and discussions on how welding can change the microstructure in the heat affected area, fabricating either extreme hardening or softening, and how these changes generate potential weaknesses that can lead to failure. To understand the effects of microstructure on the mechanical performance of welds, it is important to recognize microstructural differences at the various weld regions. These include the base metal (BM), heat affected zone (HAZ) and fusion zone (FZ). The FZ is created by heating above the melting point, while the surrounding HAZ material itself consists of several regions which experience thermal cycles with progressively decreasing peak temperature from the fusion boundary.This book will be of valued for students and practitioners requiring information on the welding and joining of advanced high strength steels. Researchers and engineers within the steel and automotive industries will find it informative.

"The application of friction stir spot welding (FSSW) for joining advanced high strength steel (AHSS) offers improvements in automobile fuel economy and crashworthiness. FSSW is a solid-state process and therefore bypasses liquid phases that form during conventional resistance spot welding. This process eliminates detrimental solidification weld defects such as cracking and debonding. A hybrid hi-material FSSW tool comprised of cobalt-cemented tungsten carbide (WC-Co) was bonded to a tungsten-nickel-iron heavy alloy (WHA). A unique sinterbonding process was used to bond the two materials. Sinterbonding WC-Co powder to WHA, using hot pressing to apply pressure, resulted in an ideal consolidated interface. Thermodynamic analyses showed cobalt-rich eta-phase carbides are favored to form at the interface due to a reduction in carbon activity. The mechanical performance of FSSW welds on various AHSS was evaluated. For constant FSSW parameters, martensitic AHSS (M190) did not result in higher lap shear strengths (LSS) compared to dual phase AHSS (DP 590) which has less than half the tensile strength M190. The results suggest that higher strength materials are more resistant to material flow under the tool during welding, which results in smaller bonded regions and LSS. The formation of a strength-reducing soft ferrite layer originating from the sheet faying surfaces was investigated for a martensitic AHSS. A series of welds with varying process times (i.e., varying total energy input) was performed to investigate welding parameter effects on the ferritic layer formation. For the conditions explored, the extent of ferrite formation was dependent on oxygen availability"--Abstract, leaf iv.
