6. WELDING PROCESS MIG / MAG
Welding
gas-shielded arc (designated MIG / MAG)
is
one
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.
Primary shielding gases for welding MIG inert gases such as argon, helium, and active gases in the MAG
CO2, H2, O2, N2 and NO, used alone or as additives in an argon or helium.
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.
MIG SINGLE PULS
Pulse MIG welding is a sophisticated form, which utilizes the best form of the transfer of the molten electrode material
on the work piece. In contrast to short-circuits, pulse welding spatter does not produce or threaten to cold "dociekiem."
In pulse welding positions are limited, as are derivatives of globular or spray forms, and their use is far more efficient.
With the cooling of the arc spray process, a pulsed MIG is able to expand the range of welding, a smaller heat input
does not cause the problem of burn-through thin materials. MIG PULSE is one of the best welding processes for a
wide range of applications and types of metal.
