Description:SJ301 is defined as a kind of bonded fluxes of silicon-calcium type.Its alkali degree is 1.0. They are gray ball grains the size of which are from 2.0-0.28mm(10-60 meshes).It adopts AC/DC.The filler-wire is connected to the positive rod when DC.It has the features of steadily burning of arc,good slag detachability,and nice welding line configuration.It especially suits to be used in various conditions,It forms short slag without the phenomenon of slag-flow.
Applications:Matching with proper filler-wire(H08A,h08MnA,H0MnMoA),it can be used to weld common steel structures,boiler steel structures and pipe line steel etc.It can be applied to multi-line welding,double-face single way welding,multi-wire welding and particularly for the welding of pipelines in various diameters.
