摘　　要：EPR机组核电站蒸汽发生器与ARE系统相连的管道接头处焊缝为低合金钢20MnD5与碳钢1.0565之间的异种钢焊接,其中低合金钢20MnD5为RCCM特有材料。通过焊接工艺评定确定氩电联焊的合格焊接工艺,以及产品见证件验证制造工艺的一致性,实现了良好的焊接质量。The joints between the steam generator and the ARE pipeline system in EPR nuclear power plant are welded with dissimilar steels between low- alloy steel 20MnD5 and steel 1.0565,where 20MnD5 low- alloy steel is a special material by RCCM.Argon arc welding procedure was defined by welding procedure qualification,and the production welds are prepared as evidence of the consistency and quality of the production welds.
