0Cr18Ni9不锈钢复合板复层缺陷修复技术

Repair Technology for the Cladding Defects of 0Cr18Ni9 Stainless Steel Clad Plate

通过不同的手工电弧焊焊接工艺修补不锈钢复合板复层缺陷,并对修复的复合板进行化学成分、力学性能、显微硬度、金相组织、能谱等检测分析,结果表明,过渡层用309焊条、复层用308焊条、分两层修补的焊接工艺二修复的缺陷区,其力学性能及耐腐蚀性能满足复合板母材性能要求。

The cladding defects of stainless steel clad plate were repaired by different manual arc welding processes.And then the chemical composition,mechanical properties,microhardness,microstructure and energy spectrum of the repaired clad plate were checked and analyzed.The results showed that the mechanical properties and corrosion resistance of the defect area repaired by No.2 welding process,that is,two layers weld,using 309 welding rod in transition layer and using 308 welding rod,met the property requirements of the stainless steel clad plate.
