摘要
Disclosed is a self-shielded flux core arc welding electrode comprising an iron metal sheath and a core in a sheath that includes a core component, the core component being about 2.0-3.0 wt% [Al], [Mn] 0. 001-0.11 wt% and rare earth metals such as La, Ce 0.001-0.11 wt% or rare earth metal oxides 0.001-0.5%, but limited to such rare earth examples Not. Includes compositional ranges of aluminum, manganese, and rare earth metals in the wire. The weld formed is comprised of Al 0.7-1.0% by weight and Mn 1.1-1.5% by weight. The weld formed has a maximum diffusible hydrogen content of 5 ml / 100 g or less. Also, the weld that is formed has a Charpy V-notch toughness of at least 100 ft-lbs at −40 ° F. [Selection] Figure 1
