Cellulosic welding electrodes contain a high proportion of cellulose in the coating and are characterised by a deeply penetrating arc and a rapid burn-off rate giving high welding speeds. Weld deposit can be coarse and with fluid slag, de slagging can be difficult. These electrodes are easy to use in any position and are noted for their use in the ‘stovepipe’ welding technique.
These electrode coatings are designed to operate with a definite amount of moisture in the coating. The coating is less sensitive to moisture pick-up and does not generally require a drying operation. However, drying may be necessary in cases where ambient relative humidity in which the electrodes have been stored in, has been very high.
