RIDGID E7018 5 lb. (2,27 kg) 1/8 in. (3,2 mm) stick electrodes. Low hydrogen electrodes reduce the potential for hydrogen-induced cracking in the weld metal, particularly in high-strength steels and other susceptible materials. Commonly used in high stress joints such as structural steel, pressure vessels, pipelines and offshore structures. Suitable for flat, horizontal, vertical and out-of-position welding.
