Product Description

 

E7018 Welding Electrode

Features & Applications:
Its nominal deposited efffciency is about 110%. The weld metal shows excellent low temperature toughness and high crack resistance. It is widely used in important structures fabricated by equivalent tensile strength mild steels or low ally steels such as ships, boilers, high pressure vessels, bridges, skyscrapers, offshore drilling platforms, nuclear power plants and so on. It has been appointed to be honor consumables by almost all nuclear power projects in China due to its faithworthy quality.

Notice:
1) The rod should be baked at 400ºC for 1-2 hours before use.
2) The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
3) Short Arc and narrow-gap welding is recommended.

E6010 Welding Electrode
Features & Applications: It is mainly used for backing welding of substrate, root passes, ffller and cosmetic welding of mild steel pipes. It could be fashioned by one-side welding with back formation.
Notice:     1) Good condition of packaging and storage for it is important.     2) Normally it does not need to re-dry. When it is damped seriously re-bake it at temperature of 70ºC -80ºC for 0.5-1 hour before welding.     3) To increase performance of welding, when using dia. 5.0mm one, bigger thrust and smaller current are recommended.
