MIG welding, also referred to as Metal inert gas welding is probably one of the easiest and cost effective welding methods. Although, it takes certain practice to use the hand-held torch for joining two metal pieces, but it offer the greatest versatility for the welding. Also, the process consumes less time to get the job done.

Working

All welders function with the same mind set of joining similar types of metal together by melting them at a high temperature and adding a filler into the molten pool of metal for extra strength. Known as fire weed welding, MIG welding make use of a wire that is fed from a spool and through a centre tip on the hand-held torch. A button on the torch pushes the wire into the molten pool that increases the level of electrical current to melt the metal. Generally, an argon inert gas is blown into the small welding area, which keeps the air impurities away from the molten metal puddle. This combination of wire feed, electrical current and the inert gas stream is used for a fast and an efficient welding process.

Types

No doubt, through this type of welding, you can not only ...
... weld carbon-based steels but aluminium as well. The wire used can be changed from that of steel welding to the kind of gas that is used for the inert gas stream. Also, some of the inert gas manufacturers offer different combinations of gas for different metal welding processes.

Size

MIG welders vary according to the size, right from the heavy industrial machines to the home based equipments. Welding equipments for the home or small shop units are almost available in the the size of 12-pack cooler that are easy to carry.

Specifications

This type of welder can be identified by the spool attachment, which contain the wire used as the filler for the welding process. Some machinery consists of the spool drive mechanism that is attached inside the welding unit. While, other equipments have a torch attachment on the torch head itself. As a fact, the torch-attached spool arrangement can be a little heavy in practice.

Gas regulator is another major component of identification in MIG welding. It controls the overall pressure and flow of the gas, which is generally held in a high-pressure tank or container. The welding process requires a pressure of 20 to 30 pound per square inch (psi), while the tanks may contain 2,000 to 3,000 psi. Always, remember that the high pressure tank allows large storage capacity in order to perform long welding process.
