摘　　要：为具体研究双相钢DP1000电阻点焊的过程,提高电阻点焊焊点质量,本文运用有限元分析软件ANSYS12.1仿真模拟DP1000钢的点焊过程,展示电阻点焊中电极与工件、工件与工件贴合面的接触应力情况和双相钢点焊过程中熔核的形成过程。模拟结果与实验相比较,分析可得理论值基本可靠,可为实际生产提供参考。For the specific study of dual phase steel DP1000 resistance spot welding process, to improve the quality of resistance spot welds, the spot welding process of DP1000 steel was simulated with ANSYS12.1 finite -element analysis software, showing resistance spot welding electrode and the workpieee, and formation of the bonding surface of the workpiece contact stress situation and duplex steel spot welding process nugget. Compared with the experimental results, the simulation results and experimental results are basically consistent.Theoretical analysis can be basically reliable, which may provide reference for actual production.
