6. WELDING PROCESS MIG / MAG
Arc welding shielding gases (indicated by MIG / MAG) is one of the most widely used process for producing weldments.
Abbreviation MAG (metal active gas) includes in its description of the active shielding gases. Abbreviation MIG (Metal
Inert Gas), refers to inert gas shroud. Semi-automatic welding process involves melting the edge of the work piece and
the material of the consumable electrode arc heat glowing between the electrode in the form of a solid wire and the
welded workpiece, in inert gas or active.

The consumable electrode is in the form of the solid wire, typically having a diameter of 0.6 to 1.2 mm and is fed
continuously by a special supply system, a speed of 2.5 m / min and above. The welding may be water-cooled or gas
shielding. Welding is carried out mainly constant current of positive polarity as a semi-automatic welding,
mechanized, automated or robotic using specialized equipment. Glowing shield arc between the consumable
electrode and the weld material for forming the weld in a very favorable thermal and chemical conditions. Welding of
this type can be used to make high quality of the connections of all the metals which may be joined by arc welding.
These include: carbon and low-alloy steels and corrosion resistant.
