Atom Arc 8018 electrodes deposit 1% Ni weld metal. They are used primarily to weld high-tensile steels in the 70-80 ksi (483-552 MPa) tensile strength range, especially where notch toughness at temperatures as low as -40 deg F (-40 deg C) is required
- Moisture resistant coatings are incorporated in all AtomArc® electrodes, flux coatings are manufactured to effectively resist moisture pick-up in opened containers, improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
- 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
- Flat, horizontal, vertical up, overhead welding positions
- Medium penetration
- 3.1 lb/hr at 140 amp, 3.8 lb/hr at 170 amp deposition rate, 75% at 140 amp, 73.5% at 170 amp efficiency
