二氧化碳气体保护焊是现今应用最广泛的焊接方法之一。它具有非常大的灵活性,可焊接大多数金属,适用于各种焊接位置,而且既可焊薄板也可焊厚板。另外,这种焊接方法的设备投入相对较低。因此,广泛用于轨道车辆制造业。CRH5型车转向架横梁管座焊接,焊缝对接接头不良的问题,造成横梁管座焊缝易出现裂纹,给横梁管座焊接质量留下不安全隐患,经过大量的工艺试验和实际焊接最终成功完成了项目攻关。
Carbon dioxide gas shielded welding is one of the most widely used soldering methods today. It has great flexibility to weld most metals, to a wide range of welding locations, both solderable and welded. In addition, this method of welding equipment investment is relatively low. Therefore, it is widely used in rail vehicle manufacturing. CRH5-type truck bogie beam tube welding, butt joints bad weld problems, resulting in cracks easily cross-beam weld pipe, weld quality to the beam tube left unsafe hidden dangers, after a large number of process tests and the actual success of welding Completed the project tackling.
