|Welding rod coated with fluxing material is not used in shielded arc welding.|

|What is right answer of this question?|
|Devendra Mishra said: (Jun 22, 2016)|
|Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
The workpiece and the electrode melts forming the weld pool that cools to form a joint. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.
So answer C is right.

|Name the material which is used for flux material?|
|Sachin said: (Dec 23, 2018)|
|Flux is a mixture of silica oxide, calcium carbonate, manganese ore and dolomite.
Flux = sio2 + CaCo3 + Mn.
