Industrial pure zirconium R60702 is a rare metal, has good weld ability and corrosion resistance, and its melting point, hardness and strength are very high. In this paper, element composition and corrosion resistance of zirconium R60702 weld seam after tube plate angle joint were analyzed. Through the polarization curve and AC impedance graph respectively characterize the corrosion resistance of the zirconium weld joint at 30℃and 70℃.
