AWS A5.17 F7A6 EH12K welding fulx xiang welding is an agglomerated aluminates basic flux, with little weld metal alloy pick-up of Mn and Si. Suitabie for welding non-and low alloy steels with single and multiple wires application. Designed for two-run or multiple layers with both AC and DC technique. Has excellent slag detachability and good operation performance. Good mechanical properties at low temperatUreS can be achieved if it is combined with appropriate wire. It is suitable to be applied in fotlowing industries.

Notes on usage:
1. The flux must be re-dried at a temperature of 300—350℃ for 1—2hr holding time when it is affected by moisture pick-up.
2. Adding proper quantity of new flux with the used one to maintain good quality of weld metal.
