Where is MIG welding used in automotive manufacturing?

MIG (Metal Inert Gas) or GMAW welding is used where continuous welds are needed: Subframe and suspension component fabrication, exhaust system assembly, seat frame welding, structural reinforcements, and repair operations. MIG provides deeper penetration than spot welding, suitable for thicker materials and structural applications. It can be robotically automated or performed manually. Parameters include wire feed speed, voltage, travel speed, and shielding gas composition. MIG creates visible weld beads requiring consideration for appearance and corrosion protection. Compared to spot welding, MIG is slower but provides continuous joints.
