Identifying Electrodes
- How the identification looks: EXXXX
- (the “X” symbolizes the numbers)
- All electrodes start with an “E” to show they are electrodes
- The fist two numbers are the minimum tensile strength
- The third number is the position a welder can us the electrode
- The fourth number is the type of flux coating, penetration, and current
Example
E7018 Welding Electrode
- E is for Electrode
- 70,000 psi tensile strength and 57,000 min. yield strength
- 1 is for flat, horizontal, vertical, and overhead
- 8 is for Low Hydrogen, Iron powder, Medium penetration, and AC, DCEP current
Basics of SMAW
- Shielded Metal Arc Welding can also be referred to as Stick Welding
- Electrodes used in SMAW can also be referred to as rods or sticks
- Stick welding can be used outdoors and on metal that is rusty or dirty
- Can be used for most common metals and alloys
- Stick welding is very portable such as inside, outside, production line, or on the job site
