Atom Arc 7018 is an all-position low hydrogen moisture resistant electrode. The wider operating ranges and smooth weld metal transfer minimizes post weld clean up. This premium quality electrode meets a multitude of codes and welding specifications. Atom Arc 7018 was developed to weld carbon and low-alloy steels, including a variety of hardenable steels
- Easy slag removal
- Capable of x-ray quality and excellent impact properties
- Premium arc performance
- For welding hardenable steels, cold rolled steels, or other steels, low alloy and mild steels when stress relieving normally would be required but cannot be done, all-position welding, general fabrication, power generation, petrochemical, pressure vessels, pressure piping
- 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
