welding rods AWS E7018
Electrode E7018
welding rods AWS E7018 is a low-hydrogen-potassium-iron-powder coated carbon steel electrode. The iron powder in the coating increases the deposited rate. It has very good usability that enables it to have stable arc, low-spatter, removal of slag is easy and performs all-position welding. The deposited metal has good mechanical properties that offer very good low temperature toughness.

Notes:
1. The electrode must be preheated at the temperature of 350°C for 1 hour. Preheat the rod whenever it is used.
2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.
3. Short arc is required to perform welding. Narrow weld path is preferred.
