What is the difference between welding electrodes E316L-15 and E316L-16?

In the model numbers, -15 and -16 indicate a welding rod structure; these are also referred to as A022 and A027. The “5” denotes that the coating type is alkaline and the current type is direct current； “6” indicates that the coating type is rutile, and the current type is alternating current or direct current.
