Abstrakty : Friction Stir Welding (FSW), provides an alternative to MIG and TIG welding methods for joining aluminium alloys. The article presents the results of electrochemical corrosion resistance test of alloy AW- 7020M and its joints welded by FSW. The study was performed using the method of electrochemical impedance spectroscopy (EIS). Impedance spectroscopy studies showed that both, the FSW welded joint and base material AW-7020M has a good resistance to electrochemical corrosion in sea water environment, wherein the welded joint has a higher susceptibility to this type of corrosion. Research has indicated the desirability of applying the FSW method for joining AW-7020M alloy in shipbuilding industry.
