WHAT ARE THE PROS AND CONS OF MIG WELDING?

MIG PROS

· Shorter time – MIG creates welds in a shorter amount of time.

· Less Costly – This process is not as expensive at TIG welds and the required equipment is more accessible.

· More accurate – It is easier to get an accurate bond with MIG welding.

· Cleaner – This method produces a clean weld with little post-weld maintenance required.

MIG CONS

· Weaker Strength – MIG is typically not as strong as TIG welding.

· Less Reliable – This weld method’s reliability can be problematic due to factors such as decreased arc stability and wire burn-back.

· More Hazardous – MIG welding can produce heavy smoke and fumes — and potentially sparks.

· Rust – This method can cause rust deposits.

· Required Thickness – With thin materials, MIG welds could potentially burn through the metal.

· Environmental Limitations – This method is hard to use outdoors because of the gases involved.

· Requirement of Different Materials – MIG can weld many metals, but they each have specific requirements for wires and gases.
