Description
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.
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 includes low-alloy structurals, low, medium and high carbon steels, offshore rigs and power plants, steel structures and tack welds for tubular wire applications.
Low Hydrogen Content
Ideal electrode for tack welding
Ideal for repairing many cracking issues
H4 electrodes have low hydrogen content which make them resistant to cracks and allows them to form stronger welds for a longer period of time.
