State the four advantages of MIG welding.  

1 Answer

Answer :

Four advantages of MIG welding: 1. High quality welds can be produced much faster. 2. Flux is not used there is no chance for the entrapment of slag in the weld metal resulting in high quality welds. 3. The gas shield protects the arc so that there is very little loss of alloying elements. Only minor weld spatter is produced. 4. It can be used with a wide variety of metals and alloys. 5. Least expensive and highly economic. 6. Little or no post welds cleaning.
