An Agglomerated Manganese-silicate type submerged arc welding Flux for High Speed Welding
F7AZ-EL8 , F7A2-EM12K
RAAJ MLET 6 is an agglomerated acidic Si, Mn alloying Rutile -Aluminate type Flux specially designed for butt and Fillet welding high speed type.
RAAJ MELT 6 is suited for SAW welding for low, medium tensile steels and for welding pipes. The Flux exhibits excellent slag removal and exceptional bead finish. The Flux also is associated with acid slag system, allowing high speed coupled with significant Si, Mn pick up, where butt welding is involved with medium this plate subjected to single or small number of passes, with no risk of any type of weld defect.
RAAJ MELT 6 possesses all excellent welding properties associated with acid slag system and hence very much suitable for high travel speed welding such as spiral welding of pipes where weld shape, easy slag removal and surface finish are necessary. The Flux is specially designed for said applications and contribute also for ‘ECONOMY WELDING’
