药芯焊丝CO2气体保护焊综合了焊条电弧焊和普通熔化极气体保护焊的优点。药芯焊丝CO2气体保护焊的推广应用,必将极大地提高工程焊接质量及施工生产效率。各类焊工技能大赛无疑为提高焊工培训质量,加大技术交流,全面提高焊接技术人员及焊工的素质起到了很好的作用。结合焊工比赛实践,具体就药芯焊丝CO2气体保护焊—管45°对接焊(φ159mm×8mm)项目,对技能培训中的焊前准备、焊接特点、焊接工艺参数、操作技术要领、焊后检验、典型缺陷预防等方面作了介绍。
The flux-cored wire CO2 gas shielded welding combines the advantages of electrode arc welding and ordinary fusion gas shielded welding. The popularization and application of flux cored wire CO2 gas shielded welding will surely greatly improve the welding quality and construction production efficiency of the project. All kinds of welder skills contest undoubtedly to improve the quality of welder training, increase technical exchanges, improve the overall quality of welding technicians and welders played a very good role. In combination with the practice of welder competition, the project of CO2 gas shielded welding-tube 45 ° butt welding (φ159mm × 8mm) for the flux-cored wire was conducted. The welding preparation, welding characteristics, welding process parameters, operation technique, , Typical defects prevention and other aspects were introduced.
