Welding flux

This granular material plays a crucial role in protecting molten metal and aiding in metallurgical treatment during welding.

Welding flux is commonly used in the joining of metal. Flux is used to promote the fusion of metals and is prominently used within the welding industry. Welders use it to prevent oxidation of both the base and filler materials used during the welding process.

Welding flux is almost inert at room temperature but is rapidly reduced when it is exposed to high temperatures. It dissolves the surface oxides and acts as an oxygen barrier to minimize oxidation.

Flux helps the flow of molten metal stay in place. When the arc process begins the base metal melts and the flux begins to enter the weld pool or weld puddle.
