E9018-G Welding Rod for High Tensile Strength Steel (CHE608)

E9018-G is used for welding structures made by equivalent tensile strength medium carbon steels and low alloy steels, such as 15MnVN steel.

Type of Convering: Low hydrogen, potassium, iron powder, iron powder.

Welding Position: F, H, HF, OH, V

Type of Current: DCEP or AC

Note:

  • The rod should be baked at 350℃-380℃ for 1 hour before use.
  • The surfaces to be welded must be cleaned away impurities, such as oil contamination, rust, moisture and so on.
  • Short arc and narrow-gap welding is recommended.
