Verified Answer
Submerged arc welding process is done with________a)flux coated wireb)...
- In submerged arc welding (SAW) the arc and weld zone are completely submerged under a blanket of granulated flux, instead of shielding gas
- Granular flux provides shielding to the weld pool from atmospheric gases and control of weld metal composition through presence of alloying element in flux
- A continuous wire electrode is fed into the weld
- This is a common process for welding structural carbon or carbon-manganese steelwork

Understanding Submerged Arc Welding (SAW)
Submerged Arc Welding (SAW) is a highly efficient welding process known for its deep penetration and minimal spatter. It utilizes a granular flux that plays a crucial role in the welding operation.
Why Granular Flux is Essential
- Protection: The granular flux covers the molten weld pool, shielding it from atmospheric contamination. This prevents oxidation and other reactions that could compromise the weld quality.
- Heat Retention: The flux retains heat, which helps maintain a stable temperature during the welding process. This is vital for achieving optimal weld penetration and fusion.
- Slag Formation: Upon cooling, the flux forms a layer of slag that protects the weld bead as it solidifies. This slag can be easily removed after the welding process is completed.
Comparison with Other Options
- Flux Coated Wire: While flux-coated wires are used in other welding methods like FCAW, SAW specifically employs granular flux for its unique benefits.
- Gas Shielding: Unlike processes that utilize gas shielding (like MIG welding), SAW is entirely submerged under flux, eliminating the need for gas.
- Flux Paste: Flux paste is not practical for the submerged arc process, as the granular form is necessary to cover the weld pool adequately.
Conclusion
In summary, the correct answer is option 'D' - granular flux cover. This choice is essential for achieving the high-quality welds that SAW is known for, making it a preferred method in various industrial applications.
