Often referred to as: Electrodes, Rods, Sticks
Have two parts
Inner core wire
Carries welding current
Serves as filler metal in the finished weld
Outer flux coating
Serves as an insulator
Provide a slag cover to protect bead and slow cool rate
Provide protective gas shield
Provides some alloying elements
Arc stabilizer

The AWS uses letters and numbers in a code that gives an electrodes important information.
E Arc welding electrode
R Heated by source other than electric current (rod)
ER electrode or rod
EC composite
B Brazing rod
RB electrode, rod, or both
RG primarily oxy fuel welding
IN consumable insert – placed in the root to serve as filler and support root pass
EW non-consumable tungsten
F flux used for SMAW

Tensile strength is given in pounds per square inch and is obtained by adding three zeros to the number given
The next number to the right of tensile is weld position
1
all position
2
horizontal fillers and flat
3 flat only
4 flat, horizontal, overhead, and vertical down
The last two numbers indicate flux type and current type
