Abstract
The contents of Cr, Fe, Mn, Ti, Si, Cu, N, Al, C, Mg, Mo, B, Zr, and Nb+Ta in a Ni-base alloy weld metal are properly specified and the contents of Co, P, and S in incidental impurities are controlled. In particular, a weld metal having high cracking resistance is formed by specifying the Mn content in a proper range and restricting the contents of B and Zr at low levels. Regarding a Ni-base alloy covered electrode, by specifying the contents of a slag-forming agent, a metal fluoride, and a carbonate serving as flux components in proper ranges and controlling the contents of Mn, Nb+Ta, and Fe in a flux, good welding workability is achieved and a weld metal having good bead appearance is formed.
