Abstract

The corrosion behavior of welding seam of the Q235 steel jointed by J420 electrode in ammonium sulfite solution was researched.The results of electrochemical method of welding seam and metallurgical structure analysis showed that the poor corrosion resisting property was determined by its structure after the Q235 steel was jointed by J420 electrode.The sulfite corrosion rate was accelerated by increasing the temperature and concentration of ammorium.
