NCPWB Technical Bulletin: When To Use E6010 Welding Electrodes

The E6010 electrode is a wire encased in cellulose held together with salts and minerals. These electrodes penetrate better than low-hydrogen electrodes like E7018 when making root passes, making it easier to make a good root pass. However, E6010 introduces hydrogen into the weld creating a risk of cracking, and this article shows when its use should be limited.
