Welding and Joining of Advanced High Strength Steels (AHSS): The Automotive Industry discusses the ways advanced high strength steels (AHSS) are key to weight reduction in sectors such as automotive engineering. It includes a discussion on how welding can alter the microstructure in the heat affected zone, producing either excessive hardening or softening, and how these local changes create potential weaknesses that can lead to failure. This text reviews the range of welding and other joining technologies for AHSS and how they can be best used to maximize the potential of AHSS. Reviews the properties and manufacturing techniques of advanced high strength steels (AHSS) Examines welding processes, performance, and fatigue in AHSS Focuses on AHSS welding and joining within the automotive industry

The book begins with thorough coverage of Resistance Spot Welding fundamentals and principles, including concepts such as Lobe Curves, contact resistance vs. electrode force, dynamic resistance, heat balance challenges, nugget growth, machine types and power supplies, and electrodes. Subsequent chapters address challenges and approaches to important topics of welding advanced high-strength steels, such as DP, TRIP, TWIP, and Press Hardening Steel, as well as aluminum alloys. Welding issues associated with the various coatings used on these steels are addressed. The final chapters are dedicated to weld quality, monitoring, testing, computational modeling, and common automotive production issues such as the welding of multiple sheet stack-ups and a brief overview of associated codes and standards. The second edition includes updated chapters and additional information, such as expanded information on welding aluminum to steel, a new section on alternative welding and joining methods, and updates on monitoring and control as well as welding issues associated with the latest advanced high-strength steels.

"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.

Many new, or relatively new, welding processes such as friction stir welding, resistance spot welding and laser welding are being increasingly adopted to replace or improve on traditional welding techniques. Before advanced welding techniques are employed, their potential failure mechanisms should be well understood and their suitability for welding particular metals and alloys in different situations should be assessed. Failure mechanisms of advanced welding processes provides a critical analysis of advanced welding techniques and their potential failure mechanisms. The book contains chapters on the following topics: Mechanics modelling of spot welds under general loading conditions and applications to fatigue life predictions, Resistance spot weld failure mode and weld performance for aluminium alloys, dual phase steels and TRIP steels, Fatigue behaviour of spot welded joints in steel sheets, Non-destructive evaluation of spot weld quality, Solid state joining - fundamentals of friction stir welding, Failure mechanisms in friction stir welds, Microstructure characteristics and mechanical properties of laser weld bonding of magnesium alloy to aluminium alloy, Fatigue in laser welds, Weld metal ductility and its influence on formability of tailor welded blanks, Joining of lightweight materials using reactive nanofoils, and Fatigue life prediction and improvements for MIG welded advanced high strength steel weldments. With its distinguished editor and international team of contributors, Failure mechanisms of advanced welding processes is a standard reference text for anyone working in welding and the automotive, shipbuilding, oil and gas and other metal fabrication industries who use modern and advanced welding processes. Provides a critical analysis of advanced welding techniques and their potential failure mechanisms Experts in the field survey a range of welding processes and examine reactions under various types of loading conditions Examines the current state of fatigue life prediction of welded materials and structures in the context of spot welded joints and non-destructive evaluation of quality
