Stick electrode

Stick electrode (used in manual metal arc / shielded metal arc welding) is a core wire in various sizes and thicknesses, over which the flux coating is coated.

Stick Welding

The stick welding process is usually defined as Manual Metal Arc Welding. In this method, stick electrodes are used to combine metals. Therefore, it is also called “stick welding”.

Stick Electrodes

For different metals, different grades of electrodes are manufactured according to their chemical composition such as: –

Stick Electrode coding

The coding of electrodes provides information about the strength, constituents of flux coating, nature of slag, current, polarity, weld position, etc. 

As per AWS-ASTM, the coding of electrodes are as follows:

E XX     XX  Example  E 60 10

E –>  Electrode

XX–> The first two digits indicate the minimum tensile strength of weld metal in thousands of pounds per sq. Inch. such as 60*1000=60000 lbs./sq. Inch.

X–>Last but on digit indicates the welding position. It can be represented by numbers like 1,2, and 3 which indicates that welding can be performed in any position, flat and horizontal positions, and flat position respectively.

X–>The last digit tells about the power supply, type of cover, type of arc, penetration characteristics, etc, it maybe 0,1,2,3,5 or 6
