The carbon dioxide gas shielded arc welding is a welding method is based on carbon dioxide gas as a shielding gas, welding
method. In the application of simple operation, suitable for automatic welding and a full range of welding. Welding can not have
wind, suitable for indoor operations. Because of its low cost, easy to produce carbon dioxide gas, widely used in various small and
large businesses
The carbon dioxide gas shielded arc Welding Flux(referred to as CO2 welding) of the protective gas is carbon dioxide (sometimes
using a gas mixture of CO2 + O2). Due to carbon dioxide gas thermophysical properties of the special influence, using conventional
welding power source, the wire end of the first molten metal can not form a balanced axial freedom of the transition is usually
needed to short circuit droplet necking burst off and, therefore, MIG welding free transition compared to splash more. However, if the
quality welder, appropriate parameter selection can be very stable welding process, so that splash down to a minimum. As used in
the protective gas is cheap, using short circuit transfer to weld good, coupled with the use of the wire can be no internal defects in
high-quality welded joints containing deoxidizer. This welding method has become one of the most important Welding Suppliesferrous
materials.
