Gas welding (GMAV), by definition, is an arc welding process that produces metal coalescence by heating an arc between the auxiliary metal electrode and the part. The process uses gas protection from the outside to protect the molten weld pool. Application GMAV generally requires DC + (reverse) polarity of the electrode.
In non-standard terminology, GMAV is commonly known as MIG (under inert gas) welding, and less commonly known as MAG (under active gas) welding. In both cases, the GMAV process is suitable for welding a wide range of solid carbon steel and tubular electrodes with a metal core. The range of alloyed materials for GMAV includes: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and tubular alloys for surface treatment with a metal core. The GMAV process is suitable for semi-automatic, robotic automation and hard automated welding applications. \"\"<\/p>\n

Advantages of GMAV<\/h2>\n

The GMAV process enjoys wide application due to its ability to provide high quality welded joints, for a wide range of alloys of iron and non-ferrous iron, at a low cost. GMAV also has the following benefits:<\/p>\n

\u2022 Ability to combine a wide range of types and thicknesses of materials.
\u2022 Simple equipment components are easily accessible and affordable.
\u2022 GMAV has higher electrode efficiency, usually between 93% and 98%, compared to other welding processes.
\u2022 Higher welder efficiency and operator factor, compared to other open arc welding processes.
\u2022 GMAV easily adapts to high robot speeds, heavy automation and semi-automatic welding applications.
\u2022 Possibility of welding in all positions.
\u2022 Great seam appearance.
\u2022 Lower layer of hydrogen in the weld – generally less than 5 mL \/ 100 g of weld metal.
\u2022 Lower heat input compared to other welding processes.
\u2022 Minimal splashes and slag make cleaning welds quick and easy.
\u2022 Less welding fumes compared to SMAV (protected arc metal welding) and FCAV (core arc welding) processes.
\u2022 Generally, lower cost per length of weld metal applied when compared to other open arc welding processes.
\u2022 Lower electrode cost.
\u2022 Minor distortions with GMAV-P (impulse spray transfer mode), GMAV-S (short circuit transfer mode) and STT (surface Tension Transfer \u2122).
\u2022 Resolves bad fit with GMAV-S and STT modes.
\u2022 Reduced welding fumes.
\u2022 Minimal cleaning after welding.<\/p>\n

Limitations of GMAV<\/h2>\n

\u2022 Lower thermal input, short-circuit characteristic, metal transfer mode limits its use to thin materials.
\u2022 Higher heat input and axial spray transfer generally limit its use for material thicknesses.
\u2022 The higher heat input mode of the axial spray is limited to straight or horizontal welding positions.
\u2022 The use of shielding gas based on argon for axial spraying and pulse spray transfer regimes are expensive than 100% carbon dioxide (CO2).<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
