E7018

USD $19.00

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
