Abstract
A flux-cored welding tubular electrode is provided made of a low-carbon steel strip having confined therein a uniform mixture of alloying ingredients and fluxing compounds in such proportion that substantially the total composition of the welding electrode including the low-carbon steel sheath consists essentially by weight of about 4.5 to 6% B, about 1.5 to 3.2% Mn, about 1.5 to 2.75% Ni, about 1.3 to 2.25% Si, about 0.375 to 1.2% C, about 2 to 6% of flux material compatible with the alloying ingredients, and the balance essentially iron. The composition of the electrode is proportioned such that the weld deposit produced from the electrode consists essentially by weight of about 0.4 to 0.8% C, about 4.8 to 6.2% B, about 1.6 to 3.0% Mn, about 1.6 to 2.8% Ni, about 1.4 to 2.4% Si, and the balance essentially iron.
