Calcium-Manganese Silicate type agglomerated submerged arc welding Flux for High Speed Welding

CLASSIFICATION : AWS: SFA/A 5.17 F7A0-EL8, F7A2-EM12K
B.I. = 1.10
Mesh Size : 10X60BSS (0.25-1.68mm)
Density : = 1.20 kg/dm3
CHARACTERISTICS :

Agglomerated, Natural basicity, calcium-manganese silicate type high speed welding flux with excellent slag detachability and smooth weld bead.it is welding with single and multi-wire procedure with DC or AC current, Due to high alloys the flux is welding up to 20mm in joining applications.

TYPICAL APPLICATION :

it is suitable for general construction, welding on structural steel, pressure vessels and water pipes, feasible for welding on a little rusty or oily plates also

It is suited for twin and multi wire welding and well suited in high speed welding especially for spiral pipe mills and also high speed beam welding,

Drying requirement : Redrying recommended at 350°C for 2 hour before use.
