Understanding E6013

Let's break down the significance of the E6013 classification:

The 'E' stands for electrode.
The '60' represents its tensile strength, which is nearly 60,000 pounds per square inch.
The '1' designates the rod's position compatibility. E6013 can be used in all four positions – flat, horizontal, vertical, and overhead.
The '3' signifies the type of slag, flux composition, and power supply it can handle. E6013 is suitable for both AC and DC straight, as well as reverse polarity welding.

Composition and Characteristics:
E6013 electrodes feature a flux coating composed of ferromanganese, cellulose, rutile, potassium silicate as a binder, and other siliceous materials. The inclusion of potassium compounds enables it to function effectively with low amperages and low open-circuit voltages when operating with AC. As the coating burns, it generates carbon dioxide and contains a substantial amount of titanium.

Applications:
E6013 welding rods find their utility in a wide range of applications, including:

General-purpose fabrication
Shipbuilding and repair
Metal buildings and structures
Machine parts
Thin sheet metal welding
Shaft buildup
Welding of vehicles
Repairing excessively machined or damaged mild steel
