Low Hydrogen Iron Powder
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
Features
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
2.6 lbhr at 120 amp, 2.7 lbhr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency
