AtomArc® 10018-MM electrodes are used to weld low-alloy, high-tensile steels where welds of 100 ksi (690 MPa) minimum tensile strength is required. This electrode is recommended for use in the weld repair and fabrication of Mn-Mo steel castings and armor plate
- Medium penetration
- Moisture resistant coatings are incorporated in all AtomArc® electrodes
- The flux coatings are manufactured to effectively resist moisture pick-up in opened containers
- The improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
- 4.9 lb/hr at 200 amp, 5.4 lb/hr at 250 amp deposition rate, 76.4% at 200 amp, 74.6% at 250 amp efficiency
- Flat, horizontal, vertical up, overhead welding positions
