Abstract : This report summarizes work on the causes of cracking in high strength weld metals. Hot tension and weld metal cracking studies were conducted on SAE 43XX-type steels and other selected steels. Results from these studies showed a correlation, inasmuch as an increase in carbon, sulfur, and phosphorus tended to lower hot ductility and promote hot crack susceptibility, and a misch metal addition seemed to have the opposite effects.
