Who knows the C02 gas shielded welding gas and wire consumption ratio?Who knows the C02 gas shielded welding gas and wire consumption ratio?No problem.
CO 2 gas for CO2 shielded welding, mostly industrial by-products, supplied by compression to liquid bottling. At normal temperature, when the standard bottle is full, the pressure is from 5 to 7MPa (5 O to 7 Okgf / cm2). Less than 1 MPa (10 table pressure), can not continue to use. C02 gas for welding, general technical standards for the purity of 99% or more, if used in the discovery of low purity, should be purified.CO2 gas shield welding of low carbon steel and low alloy steel, in order to ensure the prevention and blowhole weld mechanical properties with high alloy steel wire, must use manganese and silicon deoxidizing elements, at the same time should also limit the amount of carbon in the wire. The H08Mn 2SiA is widely used, mainly used for welding of low carbon steel and low alloy steel; H 04Mn 2SiTiA carbon content is very low, and contains 0.2% to 0.4% titanium elements, anti blowhole ability, with high requirements on the densification in the weld on.The specifications of CO2 gas shielded welding include power polarity, wire diameter, arc voltage, welding current, gas flow rate, welding speed, wire extension length, DC loop inductance, etc..
Depending on how you solder it, use a bottle of gas a day
1, and the current size and personal habits, as well as the cylinder is full, and the temperature, whether there is wind, have an impact on the general labor intensity of 1 bottles of gas can be used 1 to 2 days, you can use 2 sets of flux cored wire.2 carbon dioxide gas shielded welding is one of the welding methods. It uses carbon dioxide gas as protective gas for welding. In application, the operation is simple, suitable for automatic welding and full range welding. No wind during welding, suitable for indoor operation.3, welding wire is used as filler metal or as a conductive wire welding material. In gas welding and gas tungsten arc welding, welding wire used as filler metal; in submerged arc welding, electroslag welding and MIG arc welding, welding wire as filler metal, and conductive electrode. The surface of the wire is not coated with anti oxidizing flux.
