The Electrochemical Study on Corrosion of Heat Affected Zone of Stainless Steel Weldment in Seawater under Different Welding Procedures

Abstract:

The experiments were simulated based on the real environment of The East China sea. It were conducted to study HAZ seawater corrosion behaviors as well as effect of welding process on the corrosion performance of 304 stainless steel at different welding processes of argon arc welding with electrochemical technology. The results indicated that when the welding current increases, the corrosion rate of stainless steel sample will also increase while the open circuit potential will decrease. And with the increasing argon flow rate , the results will completely be opposite. The largest impedance size of the parent metal is 36.175 Ω/ cm² and the minimum impedance size of B1R is 12.531 Ω/ cm².
