Investigation on the weldability of a Zr-Ti microalloyed X120 linepipe
Three-wire submerged arc welding was utilized to weld a newly developed Zr-Ti microalloyed X120 linepipe with heat input of 21 kJ/cm. The microstructure in the heat-affected zone (HAZ), predominantly consisted of bainite, was examined by means of optical and scanning electron microscope. The average...
