: Simulates plastic deformation, electrode indentation, and contact pressure distribution between sheets. 2. Key Process Parameters & Inputs
To achieve high-fidelity results, simulations require precise input data, often sourced from databases or experimental measurements: 3D FE Simulations of Resistance Spot Welding
: Calculates current density and electrical potential distribution using a steady-state model. : Predicts transient heat transfer and Joule heating
: Predicts transient heat transfer and Joule heating , which is the primary source of melting. and the "shunt effect
3D Finite Element (FE) simulations are the industry standard for modeling the complex, phenomena inherent in Resistance Spot Welding (RSW) . Unlike 2D models, 3D simulations can accurately capture asymmetrical geometries, electrode misalignment, and the "shunt effect," where current bleeds into previously made welds. 1. The Core Simulation Framework
Modern 3D FEA software—such as SORPAS® 3D , Simufact Welding, and SYSWELD—solves for three interacting fields simultaneously:
