Atom Arc 7018-1 is an all-position, low hydrogen electrode that provides exceptional impact toughness at low service temperatures. Atom Arc 7018-1 provides smooth metal transfer, minimal spatter, and easy slag removal. Atom Arc 7018-1 is used to join a wide variety of carbon and low alloy steels. It is also an excellent choice for welding higher strength steels if undermatching welds are specified
- Smooth metal transfer keeps spatter to a minimum and the complete slag coverage is designed for easy removal
- Used to join a wide variety of carbon and low alloy steels
- An excellent choice for welding higher strength steels if undermatching welds are specified
- Flat, horizontal, vertical up, overhead welding positions
- Medium penetration
- Increased toughness (impact strength)
- 6.5 lb/hr at 250 amp, 7.2 lb/hr at 300 amp deposition rate, 75% at 250 amp, 74% at 300 amp efficiency
