405/16MnR复合板的焊接可认为是在基层上堆焊。由于基层对复层焊缝的稀释和碳迁移,在复层侧焊缝中产生马氏体组织,降低基层焊缝的熔合比和选择焊接材料是堆焊的关键。因此采用小电流、快速焊、多道焊。为保证复层焊缝良好的耐腐蚀和抗裂性能,复层的组织应为奥氏体加4%～12%δ铁素体。因此采用25-13型铬镍奥氏体焊条堆焊。 405 / 16MnR composite plate welding can be considered in the grassroots surfacing. Due to the primary dilution and carbon migration of the multi-layer weld, martensite is generated in the multi-layer side weld. It is crucial to reduce the fusion ratio of the primary weld and to select the welding material for surfacing. Therefore, the use of small current, rapid welding, multi-track welding. In order to ensure good corrosion resistance and crack resistance of clad welds, the microstructure of the clad should be austenite plus 4% to 12% δ ferrite. Therefore, 25-13 type chrome-nickel austenitic electrode surfacing.
