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.

Typical wire chemistry:
C: 0.063
Mn: 0.50
Si: 0.27
P: 0.017




Available diameters: 2.5mm, 3.2mm, 4.0mm & 5.0mm
