is MIG Welding?
stands for Metal Inert Gas welding, often called Wire-feed. It is also referred
to as GMAW (Gas Metal Arc Welding). The "Metal" refers to the wire which
is what is used to start the arc. It is shielded by inert gas and the feeding
wire also acts as the filler rod. A semi-automatic process, it is fairly easy
to learn and use (Check out our
Mig Welding Rod Ovens).
who practice mig welding are often referred to as wire-feed welders. It is used
on all thicknesses of steels, aluminium, nickel, stainless steels etc. It is most
typically utilized in commercial fabrication settings where continuous welding
is desired, and where environmental conditions, joint preparation, and materials
can be controlled.
mig weld process consists of a DC arc burning between a thin bare metal wire electrode
and the workpiece. The arc and weld area are enveloped in a protective gas shield.
The wire electrode is fed from a spool, through a welding torch which is connected
to the positive terminal into the weld zone.
welding is the most widely used process in the world today. It is a versatile
method which offers a lot of advantages. The technique is easy to use and there
is no need for slag-cleaning. Another advantage is the extremely high productivity
that mig welding makes possible.
flexible and adaptive, MIG welding is used when you wish to obtain high productivity
and high quality results. This process is also used for manual (semi-automatic)
welding or automated/robotized installations on low alloy carbon steels, high
alloy stainless steels or non-ferrous alloys such as aluminum or
welding is required by law and by insurance companies in many localities for structural
repair of automotive frames. MIG is also much easier to learn and faster to weld.
For doing other types of welding, like sheet metal, it can be a matter of personal
preference. For an auto body repair shop or a novice welder, MIG welding is a
good, practical process.
