What does "E43" and "E50" mean by welding electrodes of steel bars? What is the exact shape?
Minimum tensile strength of E43xx deposited metal 430MPa;Minimum tensile strength of E50xx deposited metal 500MPa.
The shape is the same, but the material is different and the strength is different. Marked on the electrode
E43 series:E43, the tensile strength of the deposited metal is greater than or equal to 42MPa (430kgf/cm2)?E50 series:E50 series - the tensile strength of the deposited metal is greater than or equal to 49MPa (500kgf/cm2)?Specific shape: conventional drug skin, hand welding electrode.Turn left and turn right |
