The use of E2209 as the deposited w eld metal of the transition layer also reduced dilution in the w elding of the cladding material.To ensure proper corrosion resistance，the chemical composition of the flux w ire also matched that of the 2205 cladding material（Table 7）.The pitting corrosion performance of the welded joint was consistent with ASTM standard A923-08/C，as shown in Table 8 and Fig.10.Using the above welding wire and welding process，the welded joints of the cladding material met the requirements of the ASTM standard（corrosion rate （mdd）=weight loss（mg）/（specimen area (dm2）·time（d）） ，the calculated corrosion rate should not exceed 10 mdd) .
