Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
- Moisture absorption
- Porosity and cracking
- Welding defects and rework
If you want stable welding performance, storage is just as important as product quality.
Why Proper Storage Matters
Welding electrodes and wires are highly sensitive to humidity and environmental conditions.
Especially for:
- E7018 (low hydrogen electrodes)
- E6010 electrodes
- E6013 electrodes
Moisture can cause:
Hydrogen-induced cracking
Unstable arc
Increased spatter
Storage Guidelines Frequently-used Products
1. Low Hydrogen Electrodes (E7018)
- Keep in sealed packaging
- Re-dry before use if exposed to air
Pro Tip: Even a few hours in a humid environment can affect welding performance.
Handling After Moisture Exposure (Remedial Measures)
If the welding electrodes have absorbed moisture, they must be re-baked:
300–350°C
Baking Temperature
1–2 hours
Duration
2. Rutile Electrodes (E6013)
- Store in a dry environment
- Avoid moisture exposure
- No need for high-temperature baking
3. Cellulosic Electrodes (E6010)
- Store in original packaging
- Do NOT over-dry
- Avoid excessive heat
4. MIG Welding Wire (ER70S-6)
- Keep away from humidity
- Store in original sealed packaging
- Use anti-rust protection
5. Flux-Cored Wire (E71T-1C)
- Highly sensitive to moisture
- Vacuum packaging is recommended
- Use shortly after opening
Ideal Storage Conditions
10–25°C
Temperature
Below 60% RH
Humidity
Dry & Ventilated
Environment
Avoid:
- Rain or water exposure
- Direct sunlight
- Open-air storage
Common Storage Mistakes
- Leaving electrodes exposed overnight
- Storing in high-humidity environments
- Mixing old and new stock
- Skipping re-drying for E7018
Result: Higher defect rate and increased costs
How Proper Storage Saves Money
Good storage practices help you:
- Reduce rework and defects
- Improve welding consistency
- Extend product lifespan
- Lower overall welding costs
Up to 20% Cost Reduction
Proper storage alone can reduce your total welding costs by up to 20%.
