E7018 is a low-hydrogen iron powder type electrode that produces high quality X-ray welds. It can be used in all positions on AC or DC reverse polarity welding current. E7018 is recommended for welding medium grade carbon steels where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional electrodes.
Typical Applications
Low-alloy structurals
Low, medium, and high-carbon steels
Offshore rigs and power plants
Steel structures
Tack welds for tubular wire applications
