CAUSES OF CRACKING IN HIGH-STRENGTH WELD METALS

Abstract

This report discusses an experimental investigation of the causes of cracking in high strength weld metals. Specifically, the work included hot ductility and weld metal cracking tests on special high strength steel and a metallographic examination of grain boundaries and inclusions in two of the steels. The results, although in an early stage, indicate that low sulfur contents are associateod with high hot ductility and high resistance to hot cracking. They also suggest a possible relationship between low melting intergranular films and low hot ductility.
