AWS A5.23 F8P2-EB2R-B2R welding fulx xiang welding is a high—basic agglomerated submerged arc flux. It is suitable for using DC+ single, AC single, DC+/AC and AC/AC. It provides excellent weld ability even in narrow groove. good mechanical properties of weld metal can be controlled by using the appropriate wire grade. Vv'ith combination of low phosphorous wires (TSW-E22R), the X factors can be controlled under 12ppm.

Notes on usage:
1. Dry the flux at 300—350℃ for 2—4hr holding time.
2. Adding proper quantity of new flux with the used one to maintain good quality of weld metal.
