Abstract
The invention provides a welding electrode useful for reducing nitrogen porosity in a weld. A metallic base having 1.5 to 6 weight percent titanium, balance essentially nickel is used. The resulting deposit has less than 0.5 weight percent titanium to ensure close match of tolerances. A flux is used in combination with the metallic base to control arc behavior, atmosphere content and slag characteristics.
