【Abstract】 Under the protection of 100%Ar and different proportion CO 2 shielded gas, the carbon content of the deposited metal is studied through using flux cored and solid wire for stainless steel in the paper. According to standard generation enthalpy and isothermal equation of thermodynamics, the mechanism of carbon increasing for solid and flux cored wire is discussed from the differences of welding metallurgic reaction between solid wire and flux cored wire. It is found that the mechanism that the carbon content of deposited metal of the flux cored wire for stainless steel can not be raised basically. The purpose of control carbon can be come true.更多还原
