Abstract : A heat-treatable low hydrogen electrode of MIL-8218 classification was developed, suitable for welds in 5-inch thick HY-80 steel to be quenched and tempered after welding. The electrode deposits weld metal with chemical composition slightly overmatching the composition of HY-80 steel. The electrode coating is similar to that of existing Arcos 'Ductilend' electrodes which enjoy welder acceptance in shipyards and fabricating plants throughout the country. Samples of the electrode have successfully been used to weld HY-80 forgings 5-1/2 inches thick without entrapment of slag, or evidence of cracking or porosity. Operation of the electrode is satisfactory in all positions. (Author)
