Storage handling packaging storage for mild and low alloy steel mig and subarc wires wire package type 1 wire storage conditions for all welding applications any type protect from rain or snow.
Wire should be stored at ambient conditions of temperature and humidity and dusty areas should be avoided when wire is not enclosed in some type of dust protecting packaging or equipment.
Electrodes with too much moisture may lead to cracking or porosity.
Do not use wire with visible signs of rust.
Low hydrogen electrodes must be dry to perform properly.
Checklist during welding.
Moisture resistant electrodes with an r suffix have a high resistance to coating moisture pick up.
Older wire should be redried before use.
Electrodes for shielded metal arc welding smaw or stick electrodes must be properly stored in order to deposit quality welds.
When stick electrodes absorb moisture from the atmosphere they must be dried in order to restore their ability to deposit quality welds.
Unopened hermetically sealed containers provide excellent protection in good storage conditions.
Storage procedure electrodes fluxcored wire flux moisture is still the main enemy for welding consumables.
Temperature 27 37 c relative humidity.
Temperature 17 27 c relative humidity.
These parameters include items such as wire feed speed voltage electrical stickout welding technique welding progression travel and push angles shielding gas adequate preheat and interpass temperature if required etc.

Flux cored wire should not be stored for more than 5 years.
Whenever possible the first in first out principle should be adopted.
Tubular wire packed in the original foil and cardboard box or drum require controlled warehouse conditions such as.
Check that all parameters stated in the welding procedure specification are being followed.
Cored wires should be stored in original unopened and undamaged packaging.
Welding consumables should be stored in their original unopened packaging in an area shielded from the elements.
Storage exposure to a humid environment with only a relative thin plastic foil shall be prevented.
Adequate storage handling and re conditioning of electrodes vary according to type.
