Selecting Welding Wire

When selecting a wire electrode for welding, one will most likely run into an American Welding Society (AWS) filler metal classification. A purchaser who isn’t familiar with the AWS classification system might select the wrong type of wire. If the purchaser is only familiar with gas metal arc welding (GMAW) wire and is attempting to purchase self-shielded flux-cored wire (FCAW-S), confusion may arise about the differences between the two classifications. This too could result in selecting the wrong wire electrode. To help prevent this from happening, we’ve created this welding wire reference guide to remind welders exactly what the different AWS classifications designations mean. We’ve included references for solid wire electrodes, metal-cored wire electrodes, gas-shielded flux-cored electrodes, and self-shielded flux-cored electrodes.
