| Abstract: | The corrosion resistance of the welded joints of duplex stainless steel and its research methods were introduced in this paper. Above all, in the duplex stainless steel welding process, the effects of corrosion resistance of the welded joints influenced by using different heat treatments and welding technologies were summarized in this paper. The results indicate that using the appropriate heat input, multipass welding, Ar ＋2% N2 gas mixture protection, Shielded Metal Arc Welding （SMAW） and Gas Tungsten Arc Welding （TIG） matching, could achieve a excellent corrosion resistance performance of welded joints. |
