Uses of Argon:
(i) Due to inert nature, it is used to fill electric bulb.
(ii) To provide inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys).
(iii) Pure argon is used in gas chromatography.
(iv) To handle air sensitive substances in laboratory.
(v) To protect metal surfaces from oxidation during steel welding.
