RAAJMELT-61 (AWS: SFA/A 5.17)

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

Classification:

AWS/SFA : A5.17
Grades: F7A0-EL8, F7A2-EM12K
Basicity Index (B.I.) : 1.10
Mesh Size : 10X60 BSS (0.25-1.68 mm)
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. Suitable for single and multi-wire welding with DC or AC current. Capable of welding up to 20 mm in joining applications due to high alloy content.

Typical Applications:

General construction and structural steel welding
Pressure vessels and water pipes
Welding on slightly rusty or oily plates
High-speed welding, including twin and multi-wire setups, spiral pipe mills, and high-speed beam welding

Drying Requirement:

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