Stick Electrodes

Mild steel covered electrodes (SMAW) shielded metal arc welding or more commonly know as "stick electrodes". They are identified by a system that uses the letter 'E' (electrode) followed by a series of numbers to indicate the minimum tensile strength, the position in which the electrode can be used, type of flux coating and types of welding current.

American Welding society numbering for A5.1-A5.5 carbon and low alloy steel covered electrodes: E6013

E (Electrode); 60 (Tensile strength 60,000 psi); 1 (Welding position - all position); 3 (Welding current - AC/DC reverse polarity.)

  • E6010 = designed to be used with DCRP
    (Electrode +) deep penetration, good metal transfer in vertical and overhead positions. Commonly used for welding pressure vessels, pipe and shipyards and repair work.
  • E6011 = designed to be used with DCRP (Electrode +) but can be used on AC. All positions, less penetration than 6010, Has more spatter during welding. A material choice for galvanized steel and for rusty and oily steel in maintenance and repair work.
  • E6013 = designed to be used with AC or DC either polarity. If has a shallow pointer-action and spatter is exceedingly low. It can be used in all positions, A good electrode for vertical down welding.
  • E7014 = designed for high speed welding, all positions and AC or DC either polarity. It is an iron powder electrode with smooth arc transfer. Low penetration, good for sheet metal and ornamental iron work. It has a higher deposition rate that E6012 and E6013. the coating provides good restrike characteristics and good melting.
  • E7018 = designed to be used with AC or DC reverse polarity (Electrode +) they have a low hydrogen base flux with iron powder added. It has a moderate penetration and a build up. These rods are very susceptible to moisture, which may lead to weld porosity. Commonly used for pipe, heavy sections of plate boiler work, and low temperature equipment.

AWS classification of Arc Welding Electrodes:

    Exx1x - All positions.
    Exx2x - Flat and Horizontal Positions.
    Exx4x - Vertical down position.

    Exx10 - DC, reverse polarity.
    Exx11 - AC or DC, reverse polarity.
    Exx12 - DC, strait polarity, or AC.
    Exx13 - AC or DC, strait polarity.
    Exx14 - DC, either polarity or AC (iron powder).
    Exx15 - DC, reverse polarity only (low hydrogen).
    Exx16 - AC or DC, reverse polarity (low hydrogen).
    Exx18 - AC or DC, reverse polarity (iron powder, low hydrogen)
    Exx20 - DC, strait polarity, or AC for horizontal fillet welds; and DC, either polarity or AC for flat position welding.
    Exx22 - AC or DC, either polarity (high iron oxide).
    Exx24 DC, either polarity or AC (iron powder).
    Exx27 DC, strait polarity. Or AC for horizontal fillet welds; and DC, either polarity, Or AC, for flat position welding (iron powder)
    Exx28 - AC or DC, reverse polarity (iron powder, low hydrogen).
    Exx48 - AC or DC, either polarity (low hydrogen, iron powder).
