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/E7018-1 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
