What is MIG Welding?
MIG stands for Metal Inert Gas welding, many times called Wire-feed.. Also referred 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.
The acronym MIG stands for Metal Inert Gas welding. It is also referred to as GMAW (Gas Metal Arc Welding). MIG welders are usually referred to as wire-feed welders. The word “Metal” in the process name refers to the consumable wire electrode used in the process. The wire and the weld joint are shielded by an inert gas and the wire electrode which is continuously fed into the arc and weld joint acts as the filler rod. MIG is most typically used to best effect in commercial fabrication settings where continuous welding is desired, and where environmental conditions, joint preparation, and materials can be controlled. Unlike TIG and stick welding, weld quality results are affected by more machine controlled variables: the current generating capacity of the welder, the thickness of the material to be welded, the thickness of the wire electrode, speed of travel, type of shielding gas used, flow rate of shielding gas, and (of course) the preparation of the joint (i.e., clean, properly bevel
MIG (Metal Inert Gas) welding, also sometimes called GMAW (gas metal arc welding), is a welding process that was originally developed back in the 1940’s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi automatic process in which a wire connected to a source of direct current acts as an electrode joins two pieces of metal, as it is continuously passed through a welding gun. A flow of an inert gas (originally Argon) is also passed through the welding gun at the same time as the wire electrode. This inert gas acts as a shield, keeping air borne contaminants away from the weld zone. The primary advantage of MIG welding is that it allows metal to be welded much quicker than traditional welding “stick welding” techniques. This makes it ideal for welding softer metals such as aluminum. When MIG welding was first developed, the cost of the inert gas (i.e., argon) made the process too expensive for welding steel. However, over the years, the MIG welding pro
The Gas Metal Arc Welding (GMAW) process is commonly known as the Metal Inert Gas (MIG) process. MIG welding is also referred to as short circuit transfer. The MIG arc-welding process joins metals by melting base and filler metals with an arc struck between a consumable filler metal wire and the base alloy work piece. The filler metal wire or consumable electrode is continuously fed and fused with the work piece. Externally supplied gas or gas mixtures provide shielding. In normal MIG, no metal is transferred across the arc. Metal is only deposited when the wire actually touches the work across the arc from the electrode to the weld puddle. As part of mig welding an area that you should pay attention is the welding wire you use for what job. Not all welding wire is the same and not all welding jobs are the same. As part of your mig welding accessories is the shielding gas type and also the mixtures you use. If the wrong gas type and wrong mixtures are used these can have disasturas con
