Abstract

PURPOSE:To eliminate the generation of high temp. cracking in a weld bead in titled welding using an Fe-Ni alloy wire, by contg. a rare earth metal and Al in the wire and limiting the content of Si. CONSTITUTION:A welding wire consisting of 0.001-0.20% rare earth metal by weight, 0.005-1.0% Al, 40-60% Ni and the balance Fe and contg. <=0.3% Si is used in the stage of automatic welding of spheroidal graphitic cast iron to each other or the spheroidal graphitic cast iron and steel. The rare earth metal here precipitates at the grain boundary of deposited metal and converts the low m.p. sulfide that is a cause for high temp. cracking into a stable shape and distributes the same in the crystal grains, thereby preventing the high temp. cracking of the weld bead, making the bead remarkably tough and improving the impact resistance thereof. The Al suppresses the generation of the blowhole in the deposited metal owing to its deoxidation effect, and fines the crystal grains of the weld bead, thus improving the impact resistance remarkably. The Si forms the film of silicide at the grain boundary of the deposited metal and causes the high temp. cracking; therefore, the content thereof is limited.
