Properties and Applications

Rutile type, agglomerated submerged arc welding flux, which is designed for welding of at high speeds with excellent bead appearence. Generally used in thin plates in shipbbuilding, pressure vessels, LPG Cylinders, small tanks, boiler, beams, thin walled pipes, tubes and lamp posts. Owing to Mn and Si alloys, make it suitable for carbon steel welding with single or multi-wires, in one and multi passes. Possible to use both in direct and in alternative currents. Slag is generally self releasing and slag removal is very easy in narrow fillet and root passes.
