Abstract

Plasma arc welding was applied to join AISI 304 and AISI 201 stainless steel sheets. Nitrogen was mixed in argon shielding gas to help control microstructure and improve corrosion property of the weld. It was found that increasing nitrogen in shielding gas from 0 to 12 %v/v reduced the amount of delta ferrite in austenite matrix of the weld from 20 to 16 %v/v. This indicated the role of nitrogen as an austenite stabiliser. From polarisation test in 3.5wt% NaCl solution at 25 °C, increasing nitrogen in shielding gas nobly shifted a pitting corrosion potential from 401 to 472 mV vs Ag/AgCl. This corresponded to the increase of nitrogen content in the weld from 0.11 to 0.19 wt%.
