First, select a stick electrode that matches the strength properties and composition of the base metal. For example, when working on mild steel, generally any E60 or E70 electrode will work. Next, match the electrode type to the welding position and consider the available power source.
How do I choose the right electrode?
Factors for Selecting the Right Stick Electrode
- Base metal properties.
- Tensile strength.
- Welding current.
- Base metal thickness, shape and joint fit-up.
- Welding position.
- Specification and service conditions.
- Environmental job conditions.
When to use 6010 or 7018?
E 6010 electrode can be used on painted, galvanized, and unclean surfaces, while E 7018 is used on clean or new sheet metal. E6010 is used for deep penetration welding, while E 7018 is used for welding metal that tends to crack, producing quality welds with excellent toughness and high ductility.
