American Welding Society Specifications for Electrodes

Iron and Steel Bare

Issued April 1, 1920

 

  1. General – The following specifications prefixed by the letter E are recommended for the purchase of all bare iron and steel electrodes for use in arc welding.
  2. Scope – The electrodes herein specified are recommended as covering the usual railroad, shipyard and industrial requirements as are allowed by authoritative regulating bodies, such as the American Bureau of Shipping and the Interstate Commerce Commission, etc.
  3. Material – Material made by the puddling process is not permitted.
  4. Physical Properties – Electrodes shall be made of commercially straight wire of uniform homogeneous structure, free from irregularities in surface hardness, segregation, oxides, pipes, seams, etc. Diameter shall not vary more than plus or minus 3 per cent from diameter specified.
  5. Nomenclature – The use of the prefix letter E is to indicate that the material is intended for electric welding.
  6. Chemical Composition shall be within the following limits for mild steel.

MILD STEEL

  1. Recommended Sizes – 3/32, 1/8, 5/32, 3/16 inch diameters.
  2. Uses – For welding mild steel, structural shapes, plates, bars or low carbon steel forgings and castings.
  3. Note – Under the heading “Mild Steel” two analyses of material are specified both of which are manufactured and acceptable.
  4. Surface Finish – The surface shall be smooth and free from rust, oil or grease.
  5. Tests – In the hands of an experienced welder electrodes shall demonstrate good weldability and shall pass through the arc in flat and overhead positions smoothly and evenly without detrimental phenomena.
  6. Packing – Electrodes shall be delivered in coils or in straight 14 inch lengths, packed and wrapped as follows:

(a)Bundles of 50 lb. net weight, securely wired and wrapped in heavy weatherproof paper.

(b) Bundles of 50 lb. net weight, securely wrapped in heavy burlap.

(c)Boxes or kegs of 100, 200 or 300 lb. net weight and wrapped as per paragraph (a).
