E7018 Low Hydrogen Carbon Steel Electrode Blue Demon

E7018/E7018-1 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
