Abstract
An agglomerated submerged arc welding flux which results in low weld metal oxygen and the concomitant high impact values while retaining the good welding characteristics of the lower basicity (acid) fluxes such as welding at higher speeds on various joint configurations with less undercutting and slag entrapment along with good slag removal. The flux contains high percentages of calcium fluoride and aluminum oxide in combination with other ingredients having a limited amount of available oxygen and sufficient acid components to lower the basicity index of the flux below 1.25. Additionally, no potent deoxidizers such as magnesium, titanium or aluminum are required.
