摘　　要：文章从钛-钢复合管板缺陷产生的原因出发,介绍了缺陷对产品质量的影响及修复的必要性。通过拟定的焊接工艺参数进行了钛-钢复合管板钛层的修复试验,并对焊接接头进行了宏观、硬度检查及显微组织分析。结果表明:拟定的焊接工艺参数满足钛层修复的需要,焊接接头的显微组织差异不大,接头的硬度值及耐腐蚀性符合钛-钢复合管板的使用性能。Based on the cause of the defects of Titanium-steel composite tube plate, this paper introduced the effect of defects on product quality and the necessity of repair work. The repairing experiments were carried out by the proposed welding process parameters, the macroscopic, hardness test and microstructure analysis of the welded joint were investigated. The results indicated that the welding parameters met the needs of the Titanium layer repair, and the microstructures of welded joints were not very different, the hardness and corrosion resistance of the joints were in accordance with the performance of Titanium-steel composite tube plate.
