Development and Production of Experimental High-Strength Ferritic Electrodes. Part 1.
Abstract
This report on the OSRD research project already mentioned was reviewed, and, in addition, a search of the literature was made for other information that would be useful. The data from the OSRD report form the basis of the present investigation. As already mentioned, Electrode No. 48A, developed on the OSRD project, was selected as a basis electrode for the present investigation, and the first step was to produce alternating-current electrodes which would deposit weld metal having comparable chemical compositions and mechanical properties. Experimental electrodes were therefore extruded, using the same coating compositions as for No. 48A. Moisture tests of the electrode coatings, dried at 600 deg F. and 900 deg F., gave results which were at variance with those expected, and these tests are being repeated. Four joints were then welded for all-weld-metal tension tests, using alternating current. X-ray radiographs of the four joints showed that the one made with the electrodes dried at 900 deg F. had the least porosity, while the others were all about equally porous. Trial bead deposits were also made using direct current.
