Chemical substances that can help and promote the welding process in the welding process, while having a protective effect and preventing oxidation reactions.
Flux can be divided into solid, liquid and gas. Mainly include "assisted heat conduction", "remove oxides", "reduce the surface tension of the welded material", "remove the surface oil of the welded material, increase the welding area", "prevent re-oxidation" and other aspects. There are two key functions in this respect: "removal of oxides" and "reducing the surface tension of the material being welded".
