CHARACTERISTICS :
Raajmelt-4 is an agglomerated aluminates basic type submerged arc welding flux for very high current carrying on AC and DC. It is used with operational properties for single, double and multi wire system. It gives impact resistance sub zero and minus temperature. The flux can be used with EL8 and EM12K.
TYPICAL APPLICATION :
It is used for welding general structural steels, pressure vessels, pipe steels as well as fine Grain steels, Boiler Drums etc. suitable for fillet welding and single or multi pass butt welding with low, medium and high tensile steels. Single wire tendem and multi-wire welding is possible for increased productivity.
Drying requirement :
Redrying recommended at 300-350°C for one hour before use.
