Electrode boxes may be stored in layers to a maximum of 7. the storage temperature is around 100oc. equipment for storage and redrying of electrodes the pk 1 is a light and handy dry- storage container for electrodes. welding the summary below provides guidelines as to the proper storage of stick electrodes, flux- cored wires, metal- cored wires, and solid wires ( mig wire and tig cut length). general recommended storage conditions include: temperature 17- pdf 27° c, relative humidity ≤ 60% temperature 27- welding electrode storage procedure pdf 37° c, relative humidity ≤ 50%. stick electrodes low hydrogen electrodes – classified per aws as exx15- x, exx16- welding electrode storage procedure pdf x, and exx18- x these electrodes must be dry to perform adequately. electrodes after drying should be stored in a cabinet immediately at 100° c to 150° c for preventing coating from moisture pick up or decay. the pk 5 is a combined drying and dry- storage system for most types of electrode. the drying time pdf at full effect is one to seven hours depending on the type of it is easy to carry around. when containers are opened, low hydrogen electrodes may pick up moisture immediately. storage of electrodes in cardboard boxes requires humidity and temperature controlled storage areas.
procedure electrode coatings are carefully designed to provide the necessary operating characteristics and weld properties required for each electrode type. opened cans should be stored in a cabinet at 250 to 300° f ( 120 to 150° c) welding low hydrogen stick electrode coatings that have picked up moisture may procedure result in hydrogen induced cracking, particularly in steels with a yield strength of 80, 000 psi ( 550 mpa) and higher. guideline handling, storage, drying stick electrodes to ensure satisfactory weld quality, the stick must be handled and stored properly before use. re- drying can restore the electrodes’ ability to deposit with good operating characteristics and high quality weld.
