The technical name for Gas Metal Arc Welding is MIG (metal inert gas)which is used in making metal repairs. Used in all types of welding, especially in automobile repair shops, it has proved an excellent media for this work as well as for heavy metal on construction sites and in other areas. Information on this kind of welding is available at places such as MIG Welder Downingtown.

A person can become an MIG welder either by on-the-job training or by taking classes at a community college or trade school. Those who take classes can take tests to be certified by the AWS. Those with on-the-job training can be certified by the company they work for if certain criteria are followed. It should be noted that only the AWS certification can be carried to a job with a different company.

The certification given by the American Welding Society (AWS) requires an applicant to show competency in welding techniques using various materials, including MIG. In addition, to maintain this certification it must be renewed every six months by an employer signed form. This form will indicate that the welder is still on the job and welding.

The automobile repair business has found this type of welding is excellent to use when working on damaged cars. It not only works well on thin metal but also works well with filler wire. It does not matter if the wire is solid or self-shielding.

Using the solid wire allows a cleaner weld however, a bottle of CO2 must be used for it to work. On the other hand, self-shielding wire does not require this gas but requires more cleaning when the welding is completed. Auto body repair was done with patching filler prior to the development of this type of welding and was not satisfactory in most cases.

MIG welding requires that the surfaces to be welded must be cleaned down to the bare metal whether on cars or other areas. Extreme care is taken before any work with the welder is started to be sure there is nothing flammable in the area. With the two pieces of metal placed tightly together it is a simple matter to finish the weld and grind it down to a smooth surface.

While welding is time consuming and, often, a sweaty job it is very self-satisfying. If a person has a steady hand and good eyesight it is not difficult to learn. In addition, a welder receives very good compensation for the job. More can be learned about welding and welding materials at places like MIG Welder Downingtown.
