WD-8011 Agglomerated Flux For S.A. Welding
 
Standards: GB/T 17854  F410-H1Cr13
 
Introduction
 
WD-8011 is an agglomerated fluoride-basic type flux with a basicity index of BIIW 2.6. The flux is vitelline or white spherical granular, grain size is from 10 to 60 mesh. Bulk density is low. It is suitable to small welding current which is direct, welding stick connect anode current. It has excellent welding technology properties. Regularly shaped welds are deposited without reduction of area or interface notches. Slag detachability is good. The welds are smooth and without slag residue. The solder deposited metal is the 13Cr department and Cr21Ni10 department, matching Cr13 welding stick series of solid, flux-cored,H0Cr21Ni10 and so on. It used in the alloy steel, high alloy steel, stainless steel automatic welding and hard surfacing welding, especially in repaired grindability pieces of hard roll.
 
Applications
 
Hard surfacing of rollers for continuous casting, steel rolling, transport, etc.

Notice:
 
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.

 

3. Preheating at 300~400°C before welding.
