Resistance 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 کاملResistance Spot Welding: A Heat Transfer Study
A heat transfer study of resistance spot welding has been conducted both theoretically and experimentally. A numerical solution based on a finite difference formulation of the heat equation has been developed to predict temperature distributions as a function of both time and position during the welding process. The computer model also predicts the temperature distribution through the copper el...
متن کاملPrimary Circuit Dynamic Resistance Monitoring and its Application to Quality Estimation during Resistance Spot Welding
Resistance spot welding is one of the most widely used processes in sheet metal fabrication. Improvements in quality assurance are important to increase welding productivity. Until now, quality estimation was performed using dynamic resistance at the secondary circuit, which is easily measured. However, this method has many problems when applied to in-process real-time systems. In this study, w...
متن کاملWeldability 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 کاملFeature selection for identification of spot welding processes
Process identification in the field of resistance spot welding can be used to improve welding quality and to speed up the set-up of a new welding process. Previously, good classification results of welding processes have been obtained using a feature set consisting of 54 features extracted from current and voltage signals recorded during welding. In this study, the usability of the individual f...
