AWS A5.1/A5.1M is the Specification for Carbon Steel Electrodes for Shielded Metal Arc Welding: E7018 is one of the most common used stick electrodes rods so it will be used as an example. E7018 E = Electrode, The first two digits = tensile strength minimum in ksi of the weld metal 70,000 psi in this case.E7018 The next two or last two digits give the type of coating/covering, type of current and welding position usage. E7018 The third digit of 1 = all position.7018 E = Electrode, The first two digits = tensile strength minimum in ksi of the weld metal 70,000 psi in this case.
