| Abstract: | 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 H0Cr21Ni10Ti & HJ260 welding process were adopted. |
