E6013 welding rod is considered one of the most commonly-used rods for amateurs and beginners. Hence, it is also known as ‘sheet metal rod’, ‘beginners’ rod’ or ‘easy rod’. It is a mild-steel, Rutile-based, all position and general purpose rod.
E6013 is characterized as follows:
E stands for electrode.
60 stands for tensile strength which is almost 60,000 pounds per inch.
1 stands for position of electrode. This welding rod can be used for all four positions – flat, horizontal, vertical and overhead.
3 stands with the type of slag, flux composition and power supply. This welding rod can be used for AC or DC straight as well as for reverse polarity.
E6013 electrode flux coating contains ferromanganese, cellulose, rutile, potassium silicate as a binder, and other siliceous materials. The potassium compounds allow it to operate with AC at low amperages and low open-circuit voltages. When the coating burns, the flux coating of this electrode creates carbon dioxide. It also has a high presence of titanium.
6013 welding rod has its applications in:
General purpose fabrication
Shipbuilding and repair
Metal buildings and structures
Thin sheet metal welding
Welding of vehicles
Excessively machined and damaged mild steel
It makes a good choice when there is poor fit up to the joint as it provides a stable arc. It has a quieter arc and smooth bead surface with a fine ripple profile. It deposits effortlessly, producing medium to shallow penetration. You can also easily remove the slag produced by it.
6013 welding rod is also ideal for filling on multi-pass welds which require putting one layer after another to produce the weld. It is convenient to work with this electrode when welders work with short or uneven welds that need positional adjustment.
The correct welding current or amperage primarily depends on the diameter of the electrode. The diameter can be 2.5mm, 3.15mm, 4mm and 5mm with amperage range as 80-120, 106-146, 140-180 and 180-220 respectively. Hence, it is important to adjust the settings of the amperage based on the size of the electrode and base metal. It is advisable to use a wire brush to clean the metal before welding so that penetration can happen easily and smoothly.
6013 welding rod is an excellent choice for the welders who need a versatile and deep-penetrating steel electrode with smooth and stable arc.
