Effect of high temperatures on mechanical properties of seam metal of low-carbon low-alloy steel welded joint

Abstract

The mechanical properties of the seam metal of a low-carbon low-alloy steel welded joint of the 22K type (Russian standard) have been investigated when testing for uniaxial tension in the temperature range from room temperature to 1200 °C. A comparative analysis of the changes in the structure, the strength and plastic properties of base metal and weld seam metal in the selected temperature range was carried out.
