摘　　要：通过对再生加热器封头、简体(1Cr18Ni9Ti)与法兰(15CrMo)的焊接工艺试验及工艺评定,采用A402焊条 堆焊隔离层,H0Cr21Ni10Ti焊丝+HJ260焊剂埋弧焊的焊接工艺方法,避免了Cr-Mo钢焊接时的重复预热,焊后经 100％RT+UT检验,焊缝一次合格率为98％以上。The welding of head or cylindrical shell（1Cr18Ni9Ti） and forging flange（15CrMo） of regeneration heater was performed and welding process was evaluated. The results showed that repeated preheating of Cr-Mo steel was avoided and primary pass percent of the welded seam was up to 98% according to RT ＋ UT （ 100% ） test when the surfacing buffer layer in welding rod A402 and HOCr21Ni10Ti ＆ HJ260 welding process were adopted.
