welding

The first two (2) digits of the electrode classification indicate the

• positions in which the electrode can be used

• minimum tensile strength of the deposited weld

• type of coating and operating characteristics of the electrode

• type of current with which the electrode can be used

The E7024 electrode can be used in

• all position

• flat position and horizontal fillets only

• flat, horizontal, and vertical down position

• flat, horizontal, vertical down, and overhead position

The electrode classification that indicates an electrode can use alternating current (AC) are

• E6010

• E6011

• E6012

• E6013

The last digit in the electrode classification E7018 indicates

• welding position the electrode can be used
