Weldability and Monitoring of Resistance Spot Welding of Q&P and TRIP Steels
This work aims at investigating the spot weldability of a new advanced Quenching and Partitioning (Q&P) steel and a Transformation Induced Plasticity (TRIP) steel for automotive applications by evaluating the effects of the main welding parameters on the mechanical performance of their dissimilar spot welds. The welding current, the electrode tip voltage and the electrical resistance of sheet s...
متن کاملResistance Spot Welding of Steels: Modeling and Simulation
Resistance spot welding (RSW) includes many variables that can influence the weld properties. The purpose of this study is to develop an analytical model for prediction of thermal history and weld microstructure in RSW and to find the most important process parameters that influence the weld microstructure. A one dimensional model is proposed for prediction about thermal history during cooling ...
متن کاملSpot weldability of TRIP assisted steels with high carbon and aluminium contents
We examine here the spot welding characteristics of transformation induced plasticity assisted steels, which contain d-ferrite as a consequence of their aluminium concentrations of 3?5 or 5?6 wt-% and which also have high carbon contents of 0?3 or 0?4 wt-% when compared with conventional automotive steels. The resistance spot welds are tested in both shear and crosstensile tests in order to det...
متن کاملWelding challenges facing advanced automotive steels in resistance spot welding process: A review
Nowadays, the use of advanced high strength steels (AHSSs) in body-in-white is one of the hot applied strategies which is followed by the most of the automakers. The study of weldability and weld challenges facing these steels in resistance spot welding process as the most widely used process in the assembly lines of the automotive industry is essential to use the outstanding mechanical respons...
