    CORROSION BEHAVIOR OF THE WELDING SEAM OF Q235 STEEL JOINTED BY J420 ELECTRODE IN AMMONIUM SULFITE SOLUTION

      Graphical Abstract
      • Abstract
    • The corrosion behavior of the welding seam of Q235 steel jointed by J420 electrode in ammonium sulfite solution was studied,adopting electrochemical method and metallographic analysis.The poor corrosion resistance of the welding seam was determined by its microstructure after the Q235 steel was jointed by J420 electrode.The corrosion rate of the welding seam was accelerated by increasing the temperature and concentration of the solution.
