Abstract
In a consumable welding element for depositing a weld metal bead onto a steel workpiece with the diffusible hydrogen in the weld metal being less than 2.0 ppm, the oxygen of the weld metal being less than 0.040% by weight and the yield strength of the weld metal being greater than about 85,000 psi, there is provided an improvement wherein the weld metal is a steel alloy including, as a percentage by weight of the weld metal, 0.03-0.09% carbon, 2.5-4.0% manganese, 0.01-0.05% titanium, silicon less than about 1.0%, nickel less than about 2.0%, and oxygen less than about 0.035%.
