In the GMAW electrode label ER70S-6, what does the R stand for?

Explanation:
The R stands for Rod. In the AWS electrode designation, E means electrode and R indicates the form is a rod (bare solid wire) used in GMAW with shielding gas. The S shows it’s a solid wire, 70 denotes about 70 ksi tensile strength, and the -6 specifies the deoxidizer package. So the R isn’t about ring, reserve, or reflow—it’s simply indicating the electrode’s rod form.
