Identifying Electrodes American Welding Society AWS has established
Identifying Electrodes
American Welding Society • AWS has established specific electrode classifications so that all electrodes manufactured have the same welding characteristics and usage.
E – 60 1 0 • The AWS electrode identification uses a letter and numbers. • Each has a specific meaning.
E – 60 1 0 Identifies the electrode for electric arc welding. E-7014
E – 60 1 0 Tensile Strength The amount of stress a substance can bear without tearing apart. Designates the minimum allowable tensile strength of the deposited weld metal in thousands of pounds per square inch (psi). i. e. ) The 60 series electrodes have a minimum pull strength of 60, 000 psi. i. e. ) The 70 series = ________ psi.
E – 60 1 0 Indicates possible welding positions. Three (3) numbers are used for this purpose. 1 = all positions 2 = flat or horizontal positions 3 = flat positions
E – 60 1 0 Indicates a special characteristic of the electrode. Examples -Type of coating -Polarity -Weld quality -Amount of penetration There are nine (9) numbers used for this purpose.
Type of Coating 0 = Cellulose sodium 1 = Cellulose Potassium 2 = Titania sodium 3 = Titania potassium 4 = Titania 5 = Low-hydrogen sodium 6 = Low-hydrogen sodium 7 = Iron powder, iron oxide 8 = Iron powder, low hydrogen
Current & Polarity 0 = Direct current with reverse polarity only 1 = Alternating or direct current with reverse polarity 2 = Direct current with straight polarity only 3 = Alternating or direct current with either polarity 4 = Alternating or direct current with either polarity 5 = Direct current with reverse polarity 6 = Alternating or direct current with reverse polarity 7 = Alternating or direct with straight polarity 8 = Alternating or direct current with reverse polarity
Weld Quality & Penetration 0 = High quality, deep penetration 1 = High quality, deep penetration 2 = Medium quality, medium penetration 3 = Medium to high quality, shallow penetration 4 = Medium penetration 5 = High quality, moderate penetration 6 = High quality, moderate penetration 7 = Medium penetration 8 = Shallow to medium penetration
