International Standards:EN**0 A FB 1 *7 AC H5 GB/T ********9 F4A*-H*8A AWS A5.******4 F6A*-EL8 F5A*-H*0Mn2 F7A*-EH*4 GB/T *********3 F*5A*-H*8MnMoA AWS A5.******4 F8A*-EA*-A1 Introduction WD-SJ**1 is an agglomerated fluoride-basic type soldering flux for submerged arc welding with a basicity index of BIIW 1.8. The flux is spherical granular, grain size is from *0 to *0 mesh.As weld metal is very purity, the diffusible hydrogen content in deposited metal is less than 5ml/**0g, so has very good toughness at the low temperature, therefore, crack resistance is extremely high. WD-SJ**1 assures excellent weldability, bead appearance is beautiful, slag is extremely easy to remove. WD-SJ**1 is suitable for submerged-arc twin-wire, tandem and multi-wire welding as well as for welding with the two-run technique. The special production method ensures that the flux has low moisture pick-up and granular stability. Flux shall be capable of meeting the applied requirements. As the bulk density is low, so is the consumption rate. Applications Flat butt and fillet welding of mild and high tensile strength steels for frames, bridges, pipes, pressure vessels, rolling stock, offshore structures and ships. Characteristics It has excellent welding technology properties for fillet welding of thick plates. Regularly shaped welds are deposited without reduction of area or interface notches. Blowholes scarcely occur.Satisfactory weldability and mechanical properties are obtained with heat .
