摘　　要：基于目前国内外复合钢板压力容器的研究现状,分析复合板压力容器焊缝结构、焊缝处蠕变机理以及温度和应力的影响,阐述了引入有限元数值分析对高温蠕变研究的意义。Based on the research status of pressure vessels of clad steel plates at home and abroad, the weld seam structures of pressure vessels of clad steel plates, the creep deformation mechanism at the weld seams, the influences of temperature and stress, were analyzed. The significance of using the numerical analysis of finite element for the researches of high temperature creep deformation was described.
