E7018 welding rods

AWS E7018 Welding rod is a iron powder low hydrogen type carbon steel welding electrode

Product Details

DESCRIPTION:

AWS E7018 Welding rod is a iron powder low hydrogen type carbon steel welding electrode.It can be used for all position welding with excellent performances:small spatters,easy restrike arc,high welding efficiency,fine appearance and slag easy to remove,etc.The seam weld metal shows a satisfactory plasticity,excellent low temperature toughness and high crack resistance.Both AC and DC can be applied.


APPLICATION:

AWS E7018 welding rod Suitable for welding important medium carbon steel and low alloy steel,such as16Mn steel,parts of ships fabricated by A,B,D,E grade steel as well as parts of boilers,pressure vessels and pipes.

 

ATTENTION:

a. AWS E7018 welding rod should be baked at the temperature of 350C for one hour before welding,and then use them when baking.

b. Before welding,the weld metal must be cleared away impurities,such as rust,oil,moisture,etc.

c. Short arc and narrow weld bead are recommended in welding.
