Q.	The coating material used for the electrode is termed as?
A.	flux
B.	slag
C.	protective layer
D.	deoxidiser
Answer» A. flux
Explanation: flux is a substance used to prevent the formation of oxides and the other unwanted contaminations, or to dissolve them and facilitate removal. during welding the flux melts and becomes a liquid slag, covering the operation and protecting the molten weld metal the slag hardens upon cooling and must be removed later by chipping or brushing.
