Atom Arc 7018-Mo electrodes contain 0.5% Mo as alloy addition. They are recommended for welding low-alloy, high tensile steels of 50 ksi (345 MPa) minimum yield strength and also 0.5% Molybdenum steels and pipes. They are widely employed in the fabrication and erection of boilers, pressure piping and tubing and other pressure vessel applications
- 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
- Useable on a wide range of steels
- Flat, horizontal, vertical up, overhead welding positions
- Medium penetration
- Meets most military requirements - greater toughness, lower moisture content as received after exposure, diffusible hydrogen limits for weld metal
- 1.7 lb/hr at 90 amp deposition rate, 66.3% at 90 amp efficiency
