Products >> A5.1, CARBON STEEL Covered Arc Welding Electrodes

 

E7018-1

 

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
