Which of the following welding
processes uses non consumable electrode?
LASER welding
MIG welding
TIG welding
ion-beam welding
TIG welding
Tungsten Inert Gas(TIG) welding processuses non consumable electrod.
Hence, the correct option is (C).
&Key Points:-
Some important point for TIG welding :
●Non-consumable electrode is used.
●Used for thin materials.
●Direct current straight polarity
(DCSP) is used in this process.
●In case of Aluminium and Magnesium
alloys AC current is used.
●Slag removal is not required (no slag formation).
