What is MIG welding?
The Metal Inert Gas (MIG) welding process forms an electric arc between a consumable wire electrode and the work piece. This heats the work piece metals so they melt and join. Both the wire electrode and a shielding gas are fed through the Welding Torch
MIG welding is also known as also often known as either Gas Metal Arc Welding (GMAW) or Metal Active Gas (MAG) welding.
What are the benefits of MIG welding?
Simplicity – MIG welding is quick and easy to learn compared to TIG welding.
Versatility – can be used to weld a wide variety of metals.
Speed – welding is quick compared to TIG welding.
Automation – easy to adapt for robotic automation
What are the disadvantages of MIG welding?
Limitations on location – MIG welding is not suitable for outside use because the volatility of the air can disperse the shielding gas.
Quality – MIG welding can produce more quality problems than TIG welding, the main ones being dross and porosity which can cause weaker welds.
