Product Detail

Model No.: J506Fe(AWSE7018)
Brand Name: "uniflower"

Product Description

In accordance with GB E5016, Equivalent to AWS E7016 JIS D5016
 
General Description:
UN-216Fe is a low hydrogen potassium coated type electrode of superior quality for carbon steel .The finish weld has good mechanical properties and crack resistance ,the bead surface looks neat and fine .With little spatter ,easy to remove the slag ,the electrode gives good welding technological performance .It can be used on both AC and DC .When used AC,the open circuit voltage must be more than 60V.
Before welding ,it is necessary to clean the weldpiece and remove impurities such as oil and grease rust and moisture ,and bake the electrodes at about 350℃ for one hour .
 
Applicant:
Welding of key structures of ship hulls, bridges, pressure containers of carbon steel ,middle carbon steel and low alloy steel, as well as other corresponding grade steels.
