Description

High Tensile Strength Steel Electrode AWS E***8 Product No: MWCE *****1 Standard: AWS E***8(corresponding with GB E***8) Introduction: AWS E***8 is a kind of carbon steel electrode with iron powder low-hydrogen potassium type coating. AC/DC. The deposition efficiency can be improved due to the iron powder in the coating. It has stable arc, fewer spatters, good slag detachability and excellent welding performance. The deposited metal has excellent mechanical properties. All-position welding. Uses: Used for welding carbon steel and low-alloy steel structures, such as *6Mn, etc. Chemical Composition of Deposited Metal (%) Chemical Composition C Mn Si S P Ni Mo Cr V Guarantee Value �0.*2 �1.*0 �0.*5 �0.**5 �0.**0 �0.*0 �0.*0 �0.*0 �0.*8 Mechanical Properties of Deposited Metal Test Item �b(MPa) �s(MPa) δ5(%) Akv1(J) Guarantee Value �**0 �**0 �*2 �*7(**0�) General Result **0~**0 �**0 *4~*0 *0~**0 Diffusible Hydrogen Content in Deposited Metal: �8.0ml/**0g(Glycerine Hydrogen Test) X-ray Radiographic Inspection: �Degree Reference Current (AC, DC+) Electrode Diameter(mm) �2.5 �3.2 �4.0 �5.0 Welding Current (A) *0~**0 *0~**0 **0~**0 **0~**0 Instructions: ***** electrodes must be baked under **0~**0� for an hour before welding and used as soon as baking is completed. ***** stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding. 3.When welding, short arc must be used and stringer bead is suitable.
