In which of the following welding processes, flux is used in the form ...
Submerged Arc Welding
Submerged arc welding is a welding process that involves the formation of an arc between a continuously fed electrode and the workpiece. In this process, flux is used in the form of granules to shield the arc and the molten weld pool from the surrounding atmosphere.
Flux Granules
In submerged arc welding, the flux is used in the form of granules that are fed continuously along with the electrode. These granules melt and form a protective slag over the molten weld pool, preventing it from reacting with the surrounding air. The flux also helps in removing impurities from the weld metal, improving the quality of the weld.
Benefits of Flux
Using flux in the form of granules in submerged arc welding offers several benefits. It helps in stabilizing the arc, improving the weld bead appearance, reducing spatter, and enhancing the overall weld quality. The flux also acts as a deoxidizer, removing oxides from the weld metal and preventing porosity in the final weld.
Application
Submerged arc welding with flux granules is commonly used in industries where high-quality, high-speed welding is required. It is particularly suitable for welding thick materials, as the flux helps in controlling the heat input and achieving deep penetration. This process is widely used in the fabrication of pressure vessels, shipbuilding, structural steel construction, and other heavy fabrication applications.
In conclusion, submerged arc welding with flux granules is a versatile and efficient welding process that offers numerous advantages in terms of weld quality, productivity, and ease of operation.
