Abstract EN
Manual metal-arc welding was carried out for ductile cast iron under welding conditions of (90) A DC current (DCEN) and 20 volts.
Welding wire type E- Ni -Fe- CI in diameter of 3.2mm was used and travel speed of 7 inch /min and welded through two passes.
The weld joined are examined using X-ray radiography, broken down joint are excepted.
Corrosion specimens prepared from free defects joints having measurements of (15*15*3) mm agreeing to ASTM G71-31.
Then Optical microscopy was employed to detect the welded joint microstructure and base metal.
Micro hardness was implemented using Vickers test.
Corrosion examinations are conducted using electrochemical potential state chamber in equipped (sea water 3.5% NaCl),Corrosion examination is achieved using potentiostatic polarization dimensions in saltwater 3.5%NaCl at potential scan rate (+100-100 mv/sec) to estimate corrosion parameters by extrapolating.
The corrosion rate was calculated by Tafel equation.
The results of corrosion rate can be predicted using a mathematical model using data achieved from practical method and compare these results with the theoretical one, results show that corrosion rate for welded joint is more than the base metal because of the change in metal microstructure during welding process.
