WebLow hydrogen coatings are used for all of the higher-alloy electrodes. By additions of specific metals in the coatings, these electrodes become the alloy types where suffix letters are used to indicate weld metal compositions. Electrodes for welding stainless steel are also the low-hydrogen type. WebLow Hydrogen Electrodes Cellulosic electrodes remain in favour, despite the limitations referred to above, because of their rapid welding speeds and their ability to cope with the variations in weld joint preparation which inevitably arise on site.
