Hydrogen in HY-130 Weld Metal.
Abstract
This report summarizes progress in producing evaluating welding electrodes containing known amounts of rare earth metal for reducing hydrogen embrittlement in HY-130 steel welds. Prior work indicated rare earth silicides lowered the notch strength of welds. In this report studies directed toward the use of rare earth-nickel additions as a possible means of improving this property while retaining the desirable effects of the rare earths. Results to this time indicate notch strength lowering by the rare earth-nickel also. (Author)
