Welding electrodee7018 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 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 structures
Low, medium, and high-carbon steels
Offshore rigs and power plants
Steel structures
Tack welds for tubular wire applications

E6013 is a mild-steel, all position, general purpose cellulose-base rod. It operates on ac or dc welding current and works well on low voltage ac machines. E6013 is an excellent choice where there is poor fit-up in the joint. It deposits easily and smoothly producing medium to shallow penetration. Small sizes are well adapted to low heat on thin metals. Medium to heavy slag is easily removed and provides for excellent weld cleaning action during the welding process.
