WD-8018 Agglomerated Flux For S.A. Welding
 
Standards: GB/T 17854-1999   AWS A5.9M-2006  ER2209
 
Approvals: CCS
 
Introduction
 
WD-8018 is an agglomerated fluoride-basic type flux with a basicity index of BIIW 2.5. The flux is yellow spherical granular. WD-8018 can be welded with DC at up to 1200A,connect the welding wire to the positive terminal when with DC. Grain size is from 10 to 50 mesh. This flux is for matching with ER2209 welding wire, deposited metal is pure, burning loss is low, has high tensile strength and yield strength; Test result meets AWS standard, has high content of delta ferrite, slag removal is easy in the narrow gap. 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.
 
Applications
 
Welding of petrochemical industry equipments, treatment equipments of seawater and waste water, oil and gas pipelines, ships for chemical engineering.
