The welding procedure was carried out under β-transus temperature that was consisted of equiaxed grains in the stir zone. The corrosion behavior of the welded joint was investigated in 3.5% NaCl solution at temperatures of 25, 37 and 80 . Microstructure investigation of sample surfaces after electrochemical experiments was conducted using SEM. results revealed that the β phase was mainly corroded at all three testing temperatures, however the corrosion in the sample tested at 80 °C was more considerable. %> http://jwsti.iut.ac.ir/article-1-281-en.pdf %P 123-134 %& 123 %! %9 %L A-10-335-2 %+ %G eng %@ 2476-583X %[ 2020
