WD-68 Agglomerated Flux For S.A. Welding
Standard: GB/T 12470-2003 F55A3-H08G AWS A5.23M-97 F8A3-EA3
WD-68 is an agglomerated aluminum-basic type flux with a basicity index of BIIW 2.4.The flux is black spherical granular.WD-68 can be welded with AC or DC at up to 1200A,connect the welding wire to the positive terminal when with DC. Grain size is from 10 to 50 mesh. As deposited metal is purity and SiO2 content is low, the transition of silicon is very low, so has very good toughness at the low temperature. Short slag is formed after welded, slag removal is easy in the narrow gap, and doesn’t drip slag when welding cylinders of small diameter. Bead appearance is beautiful, burn-out of the arc is stable, slag is easy to remove. The flux has low moisture pick-up and granular stability. As the bulk density is low, its consumption rate are few. With the matching wire,WD-68 is suitable for multi-layer welding, single pass welding in double side, multi-wire welding and narrow gap welding.WD-68 could be used for welding of high tensile steel for ship, steel for pressure vessel, steel for pipelines, ocean platform and fine grain structural steel.
For flat fillet and butt welding of steel for ships, steel structures, pressure vessels, storage tanks, bridges and spiral pipes.

Typical mechanical properties of deposited metal
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
