Welding which is done by using an external shielding gas to weld the metals together with the heat generated by the electric arc that is produced between a consumable electrode and the metal being welded. Deep penetration of the weld, along with rapid deposits of weld metal are provided by this process.
An arc welding process that produces coalescence of metals by heating them with an arc between a continuous filler metal (consumable) electrode and the work. Shielding is obtained entirely from an externally supplied gas or gas mixture. Some variations of this process are called MIG (Metal Inert Gas) Or CO2 welding, nonpreferred terms.
MIG welding is undertaken with direct current electricity, with argon or argon/helium mixes as the shielding gas. The welding speed of MIG is faster than for the TIG method. The speed of welding means that the size of the heat agitated area in the parent metal is smaller compared to other welding methods.
An arc welding process in which the bare wire electrode and inert shielding gas are fed to the weld through a welding gun. It is also referred to as GMAW or MIG welding.
An arc welding process wherein coalescence is produced by heating with an arc between a continuous filler metal (consumable) electrode and the work. Shielding is obtained entirely from an externally supplied gas, or gas mixture. Some methods of this process are called MIG or CO welding.
A welding process in which a piece of electrically charged wire being fed through a pistol grip type handle completes an electrical arc with the pieces being welded. The electrical arc provides the heat source and the advancing wire provides filler material for the weld bead. Simultaneously, inert gas flows through the end of the pistol grip type handle along with the wire. This inert gas floods a few square centimeters of work area to prevent the problems that can arise from oxidation. This welding process is used where deep penetration is necessary, speed in production is necessary, larger pieces are being joined, and the cosmetic appearance of the bead is of little concern. synonyms: wire feed welding, MIG welding GTAW
Gas metal arc welding (GMAW), sometimes referred to by its subtypes, metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used. There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations.
