1. Cleaning and Purification: Flux removes oxides and impurities from welding materials, ensuring weld quality.
2. Enhanced Wettability: Flux facilitates contact between the molten pool and the workpiece surface, improving wettability and making welding easier.
3. Temperature Regulation: Some fluxes help regulate temperature by absorbing and releasing heat from steam, maintaining an appropriate welding temperature.
4. Oxidation Prevention: Some components in flux prevent oxygen from entering the welding area, preventing oxidation and protecting the weld from damage.
5. Structure Improvement: Some fluxes can be added during welding to alter the physical and chemical properties of the material, enabling it to meet specific requirements.
