Abstract

Abstract: The reason of the weld seam cracks of SA213-T23 steel was introduced. The metal physical and chemical analysis for the cracked weld seam of SA213-T23 steel was carried out. Due to that the weld seam cracks have the features of reheated cracks, it related closely with the structural stress, residual stress by welding to prevent the weld seam cracks of SA213-T23 steel in the operation once more,operating the bonding technology strictly and optimizing the operation mode were suggested.

Key words: SA213-T23 steel, weld seam crack, physical and chemical analysis, treatment measure
