摘　　要：针对某企业换热器管板堆焊试验及其工艺技术方案,利用ABAQUS软件模拟在高强度基体合金材料上堆焊过渡合金材料(软质或防腐蚀),得到焊后温度场和应力场的分布规律,并用试验结果验证了堆焊数值模拟结果的合理性,确定了适合此管板堆焊的热源模型及参数。同时,堆焊动态模拟研究结果为堆焊试验提供了充分的理论依据,为优化堆焊工艺及堆焊方法奠定了基础。通过理论研究与试验验证相结合的方法,在满足管板性能及其材料强度等相关技术要求前提下,减少了试验成本和时间,缩短了生产制造周期,对制定焊接工艺有指导性意义。The article aimed at Heat exchanger tube sheet welding experiment and its processing technology programs in a certain enterprise and using the ABAQUS software to proceed simulation on high strength and matrix alloy surfacing transition alloy materials （soft or corrosion protection）, which can acquire the temperature and stress field after welding which has been testified the rationality by test result,then determining the suitable heat source model and the welding parameters. At the same time,welding dynamic simulation research result provide adequate theoretical basis for welding test and lay the foundation of optimizing the process and method of surfacing welding. Through the methods of combining theoretical research and experimental verification,under the premise that meet tube sheet properties and strength of materials and related technical requirements,which reduce test cost and time and shorten manufacturing cycle and the methods have guiding significance for establishment of welding procedure.
