Fluxes are used in welding in order to protect the molten metal and the surfaces to be joined from (1) Oxidation
Explanation for correct option
Fluxes are applied for various purposes
- To clean both the surfaces to be joined to avoid any dust or dirt within the joints.
- To facilitate the joining of molten metal to reach even the tiniest holes.
- To avoid the interference of any oxides etc. that can cause oxidation of the metal.
Explanation of incorrect option
Hence rest of the options
- (2) Carburising
- (3) Unequal temperature distribution
- (4) Distortion and warping
Are incorrect.
