Industry: structural steel, H beams welding, spiral pipe mills, bridge building, ship building, gas/oil pipeline, heavy equipment, piling pipe, etc.
Description: fluoride based agglomerated flux. Granular size 10-60 mesh (0.28-2.0mm). Easy slag removal. Excellent mechanical properties. Smooth welding pass. Widely used for API grade X60, X65, X70 pipeline construction. Low diffusible hydrogen content (≤5ml/100g) in weld metal gives it high toughness and high cracking resistance at low temperature. It is appcalible for multi wires welding, especially for double-sided single-pass welding of big diameter vessels. Welding speed is as high as 1.6--1.9m/min.
Package: damp-proof packing, 25kg/bag

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.
