AWS classifications for electrodes

How to read the AWS classifications for electrodes.

1. Flat, Horizontal, Vertical, Overhead
2. Flat and Horizontal Only
3. Flat, Horizontal, Vertical Down, Overhead



MIG: Choose the right                welding alloy 

Stainless Steel Welding - 308L is used to weld stainless base materials of similar composition including types 301, 302, 304 and 305. 309L is used when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metals. 316L is used to weld stainless 316L and 316 base materials of similar composition or for high temperature service applications.

Mild Steel Welding - ER70S-2 Mild Steel cut lengths are for general purpose mild steel applications. Triple deoxidized, for use with moderate levels of mill scale. ER70S6 mild steel wire is for general purpose mild steel applications with tensile strength exceeding 70K psi. High levels of silicon and manganese deoxidizers and is best suited for welding on base metals with medium to high mill scale.

Self-Shielding Fluxed Cored - Ten gauge wire can be used in most carbon steel applications, and welds especially well on galvanized. E71T-GS flux cored mild steel wire is a self-shielded alloy that can be used for welding in all positions of most mild steels, indoor or outdoor applications, and up to ½ thickness.

AC-225 Welding Application


STICK: Choose the right          welding alloy

6011 Stick Electrode
Great for sheet metal welding applications and AC pipe welding. Used on jobs where steel isn’t clean and weld appearance is less important.

6013 Stick Electrode
General purpose, all position electrode that has a great weld appearance. Requires a clean work surface, easy restrikes and very good operator appeal.

7018 Stick Electrode
Low Hydrogen electrode that offers superior weld strength and appearance with little slag and spatter. Requires a clean work surface.
