CO2 gas shielded arc welding is a cheap and efficient welding methods(Welding Electrodes ). CO2 welding short-circuit the traditional transition from the fundamental solution can not spatter, and the control penetration and forming of contradictions. STT Waveform Control Technology by type of CO2 welding machine, welding process to ensure stability, weld appearance, stem elongation of small change, significantly reduces splash and a welder to reduce labor intensity.
STT-type semi-automatic welding with CO2, the welder is in short circuit transfer mode, the power in a transitional period, depending on the value of the arc voltage, the output of different welding current.
STT-type CO2 semi-automatic welding broadens its excellent performance in long distance CO2 semi-automatic welding in pipeline construction applications. China Petroleum Pipeline Bureau has Muglad oil development projects in Sudan, the first use of the STT-type CO2 semi-automatic welding technology for pipeline under the backing to the welding, Zhongyuan Petroleum Exploration Bureau, construction company is double-track the construction of Beijing-Shaanxi-Beijing line - used stone pipeline project the STT-type semi-automatic CO2 welding technology to the next. Welding Table 5.
STT-type CO2 semi-automatic welding and flux cored welding wire from the protection of semi-automatic welding is currently used semi-automatic welding under the method shows good in the field of pipe welding applications.
