While both the wires are mild steel based, the coating on both are very different, the 7018 has a low hydrogen potassium coating whereas the coating on the 6013 is high Titania potassium. The electrodes also differ in yield and tensile strength, the 7018 has higher specifications in both.What is a 7018 welding rod used for?
The 7018 arc welding rod is commonly used for general-purpose welding of carbon steel. It is a mild steel rod that is coated with a low-hydrogen, iron-based flux compound that vaporizes to shield the molten weld bead from contamination by air and moisture.What is ER70S 2 welding electrode?
