WHAT IS THE DIFFERENCE BETWEEN E6013 AND6013?

The difference between E6013 and 6013 primarily lies in the designation system used. E6013 is an electrode classification that indicates the type of welding rod, where "E" stands for electrode, "60" signifies a minimum tensile strength of 60,000 psi, and "1" denotes that it can be used in all positions. In contrast, 6013 refers specifically to the filler metal without the electrode classification prefix, but it typically conveys the same properties when discussing welding rods. Essentially, E6013 and 6013 refer to the same type of welding electrode.
