To identify a low hydrogen electrode, the most reliable method is to **read the classification numbers painted on the covering near the stub end of the electrode**. These numbers indicate the type of electrode and its characteristics, including whether it is low hydrogen.
Low hydrogen electrodes are usually marked with a specific classification, such as E7018, which indicates their low hydrogen properties. While consulting with a welder or a welding foreman can provide insight, reading the markings on the electrode is the most direct and accurate method.
Looking at the completed weld to identify the electrode type is less reliable, as different electrodes can produce similar weld appearances.
