RAAJMELT-6 (AWS:A 5.17 F7A2-EM12K)

Agglomerated Manganese-Silicate Type Submerged Arc Welding Flux for High Speed Welding

Classification:

AWS/SFA : A.5.17
Grades: F7AZ-EL8, F7A2-EM12K
Basicity Index (B.I.) : ~0.80

Characteristics:

Raajmelt-6 is an agglomerated acidic Si-Mn alloying Rutile-Aluminate type flux, specially designed for high-speed butt and fillet welding. Suitable for low and medium tensile steels as well as pipe welding. The flux provides excellent slag removal, exceptional bead finish, and allows high travel speeds while ensuring Si and Mn pickup for butt welds with minimal risk of weld defects.

Typical Applications:

High travel speed welding such as spiral welding of pipes
Applications requiring excellent weld shape, easy slag removal, and superior surface finish
Contributes to “Economy Welding” in single or limited-pass welding

Drying Requirement:

Redrying recommended at 300°C for 2 hours before use.
