| Abstract: | The welding characteristic and technology of duplex stainless steel 2205 were introduced in this paper.The basic requirement of welding the steel 2205 is that the weld metal and heat-affected zone obtain a favorable phase balance and retain the performance as the base metal after welding.After the characteristic of 2205 welding metallurgy was analyzed,this requirement can be met by using highly alloyed filler metals which contain more Ni and N than the base metal and controling the welding heat input.GTAW and SMAW are suitable for welding 2205.It is by welding procedure qualification that we gain a mastery of the welding technology for this steel and guarantee the quality of welding in practice. |
