Numerical simulation and experimental test of DP590 dualphase steel welding

DP590 dual-phase steel weld temperature field was analyzed by using ANSYS softwere. A program was developed with APDL language supported by the ANSYS, combining the body heat rate and element birth and death technology to simulate the welding filling process and heat input. A butt welding experiment with the DP590 dual-phase steel (3.8 mm thickness) was done in order to verify the accuracy of the simulation calculation. It is verified that numerical simulation is feasible.
