Attention:
1.
We get values in data sheets from tests carried out in accordance to
AWS and GB standard procedure. They only represent values we get under
those conditions. They are not to be taken as guarantees. As to welding,
individual test results may vary depending on experience &
technique, flux type, base metal, joint preparation,
flux preparation, ampere, voltage, etc.
2. If welding fluxes are stored in improper environment or influenced by
condensed moisture, anyway, they get damp, please dry them at 300-350℃ for 2 hours before usage.
3. Please clean the rust, oil, water on base metal before welding.
4. Add minumum 20% new flux when using
recovered flux to avoid welding defects and maintain welding performance
& mechanical properties.
5. Please control parameters properly, like preheat temperature, interpass temperature, cooling rate.
