The differences between E43 covered electrode and E50 covered electrode are mainly in importance, minimum tensile strength and applicable conditions.

1, with different meanings:

The letter "e" stands for covered electrode; The first two digits indicate the minimum tensile strength of deposited metal; The third digit indicates the welding position of covered electrode, "0" and "1" respectively indicate that covered electrode is suitable for all-position welding, "2" indicates that covered electrode is generally suitable for flat welding and fillet welding, "4" indicates that covered electrode is suitable for downward vertical welding, e in covered electrode model indicates covered electrode, and the two digits on the right indicate the tensile strength of weld metal. That is, E43 and E50 represent different strength levels of 430 MPa and 500MPa, respectively.

2, the minimum tensile strength is different:

The minimum tensile strength of the deposited metal is different, and the minimum tensile strength of E50 deposited metal is greater than that of E43 deposited metal.

3. Different applicable conditions:

E43 covered electrode is generally suitable for Q235 grade steel, and E50 is suitable for Q345 grade steel.
