Abstract : Seven new experimental electrodes, Nos. UE-7 to UE-12, inclusive, and UE-16, were made and tested. All of them had satisfactory operating characteristics, in the downhand position, using either alternating or direct current (electrode positive). Electrodes UE-7, -8, -9, and -10 were a radical departure from the 48A weld-metal composition, in that the molybdenum content was reduced, and nickel, or nickel and chromium, were the principal alloying elements. The yield strength of these weld metals was lower than desired, but the ductility was very good. It is believed that these electrode compositions may be useful where the required weld-metal yield strength is about 90,000-100,000 psi.
