MIG welding offers advantages like high deposition rate, requires shielding gas, and demands operator skill for quality welds.
A) High deposition rate is an advantage of MIG welding as it allows for fast welding of materials.
B) Ability to weld in windy conditions is not a specific advantage of MIG welding since wind can affect the welding process negatively.
C) MIG welding requires shielding gas to protect the weld pool from atmospheric contamination, so the statement 'No need for shielding gas' is incorrect.
D) Although MIG welding is relatively easier than some other welding processes, it still requires skill and operator proficiency to ensure quality welds.
