WD-SJ501 Agglomerated Flux For S.A. Welding

タイトルまたは説明

International Standards:EN**0 A AR 1 *8 AC H5 GB/T ********9 F5A*-H*8A AWS A5.******4 F7A*-EL8 Introduction WD-SJ**1 is an agglomerated aluminate-rutile type soldering flux for submerged arc welding with a basicity index of BIIW 0.5. The flux is spherical granular, grain size is from *0 to *0 ***** is suited to twin-wire, tandem and multi-wire welding at high speeds, the welding speed is more than **0cm/min. It is particularly useful for welding tube-web-tube joints of finned tubes. It has excellent welding technology properties. Regularly shaped welds are deposited without reduction of area or interface notches. Slag detachability is good, welding blowholes scarcely ***** 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 Q**5 for steel frames, bridges, spiral pipes, pressure vessel and ships. Characteristics It is suited to welding steel plate of less than *0mm. Slag is easy to remove, bead appearance is beautiful, welding defects such as pits and blowholes scarcely occur in high speed fillet welding.
