RAAJMELT-61 (AWS: SFA/A 5.17)

Agglomerated Aluminate Rutile-Silicate Type Submerged Arc Welding Flux for High Speed Welding

Classification:

AWS/SFA : A5.17
Grades: F7AZ-EL, F7A0-EM12K
Basicity Index (B.I.) : 0.80

Characteristics:

Raajmelt-81 is an agglomerated Aluminate Rutile-Silicate type flux, specially designed for butt and fillet welding at high speed. It provides excellent slag removal and exceptional bead finish. Preferably used for welding thin plates at speeds up to 1800 mm/min.

Typical Applications:

High travel speed welding such as spiral welding of pipes
Applications requiring excellent weld shape, easy slag removal, and superior surface finish
High-speed beam welding processes using twin-wire auto systems

Drying Requirement:

Redrying recommended at 350°C for 2 hours before use.
