Abstract : This is the eight and final report on Part 1 of Contract W33-019 ORD 5461. The investigation dealt with the fundamental factors involved in producing improved ferritic electrodes suitable for use in the fabrication by metal-arc welding of high-strength (100,000 to 150,000 psi yield strength) steels, such as may be used in ordnance material, and the development and prduction of 100 lb. of experimental high-strength ferritic electrodes for delivery to Watertown Arsenal. This work was, in effect, a continuation of work conducted in 1944 and 1945 for the Office of Scientific Research and Development on NDRC Research Project NRC-76, Contract No. OEMsr-1270, Development of Improved Electrode Coatings. This summary reviews the experimental work done from May 3, 1946, to January 3, 1947, and traces the development of Electrode UE-16, which deposited weld metal with the best strength properties of any produced during the investigation. A compilation of the properties of all the electrodes developed, with the procedures used and strengths obtained, is given in Table A-2.
