Numerical Simulation of the Temperature Field During DP1000 Dual-Phase Steel Resistance Spot Welding

Abstract:

Dual phase steel resistance spot welding process is transient, rapid, invisible, complex, which makes the physical process of welding not yet be fully understood. Both the preprocessing contact stress field and thermo - electric transient process under alternative current(AC)load of the resistance spot welding of DP1000 dual - phase steel are analyzed by ANSYS12.0 finite-element analysis software. The fusion zone formation process and the contact situation of electrode and workpiece, between workpieces, lamination surface is investigated through numerical simulation. The project can help understand the phenomenon and essence of the DP1000 spot welding optimize the structure design and process design, quality control, for the dual-phase steel in vehicle body spot welding quality control to provide theoretical guidance.
