Patent ID: 8664567

Claim:
A cored metal electrode which forms a weld metal in narrow grooves having improved yield strength and tensile strength comprising of between about 0.001-0.02 weight percent boron, between about 0.05-2 weight percent molybdenum, between about 0.005-0.5 weight percent titanium and a majority of iron, a weight percent ratio in said weld metal of titanium to boron being at least about 2:1, and molybdenum to titanium being at least about 4:1, said weld metal having an average yield strength of at least about 70 ksi and an average tensile strength of at least about 90 ksi, said cored metal electrode compising: a sheath; and a fill composition inside said sheath, said fill composition containing less than 1 weight percent flux agents based on the total weight of said cored metal electrode.
