WD-8600 Agglomerated Flux For S.A. Welding

Description

Standards:GB/T********9 F4A*-H*8MnA AWS A5.******4 F6A*-EM*2K GB/T*********3 F*8A*-H*0Mn2 AWS A5.******4 F7A*-EH*4 Introduction WD****0 is an agglomerated aluminum-basic type soldering flux for submerged arc welding with a basicity index of BIIW 1.**1.3. The flux is taup or charcoal grey spherical granular, grain size is from *0 to *0 mesh.When direct current weld the wire, it meets the positive electrode.WD****0 can be welded with AC or DC at up to ***** arc stability, forming artistically, it has an excellent slag ***** weld metal is ***** has high impact ***** flux has low moisture pick-up granular stability.As the bulk density is low, its consumption rate is ***** it coordinates the suitable welding wire, it can be welded a variety of low-alloy steel wire structure.When it welds the boiler cooling wall, its welding speed may reach above *0mh/h, especially suitable high speed welding thin steel plate, narrow groove of thick plate and narrow-gap structure. Applications Welding of the boilder firm type water cool wall, high-speed flat and horizontal fillet.
