Which of the following welding method uses a pool of molten metal?
A. Carbon arc welding
B. Submerged arc welding
C. TIG arc welding
D. MIG arc welding
Answer: Option B
Solution (By Examveda Team)
This is a well established and extremely versatile method of welding. Submerged-arc welding (SAW) involves the formation of an arc between a continuously fed electrode and the work piece.A blanket of powdered flux, which generates a protective gas shield and a slag (and may also be used to add alloying elements to the weld pool), protects the weld zone. A shielding gas is not required.

- For pull off molten metal it is electroslag welding and,
- For pool of flux it is submerged arc welding
It will be Electroslag Welding
It's Electroslag welding.
