Welding Electrode Comparison: Find the Right Model and Grade

The E in carbon steel welding rod indicates the rod, the first two digits represent the minimum tensile strength of the deposited metal, the third digit represents the welding position, and the combination of the third and fourth digits represents the type of welding current and the type of coating.

For stainless steel welding rods, E stands for the rod, the numbers following “E” represent the classification code of the chemical composition of the deposited metal, and the two digits following “-” represent the type of coating, welding position, and type of welding current.

For more specifics, you can refer to GB5117 and GB983.
