中文摘要： 针对负压传感器静压腔充气小孔的封焊问题，通过具体的分析，选择了合适的焊接方法及焊接设备，并对压力传感器电弧封焊过程中出现的主要问题，即电弧的引燃和稳定性问题，提出了相应的解决措施。在进行了多次模拟焊接实验后，探索出了合适的焊接工艺、方法及参数，实现了负压传感器充气孔的高质量封焊。
英文摘要：Aiming to the sealed welding problem of sensor air hole, the suitable welding method and welding equipment was chosen, especially for the cathode materials selection of arc generator. The corresponding measures for the problems of arc ignition and arc stability are put forward, which are the main problems in the sealed welding process. After simulation experiments, the optimum arc sealing welding process for the negative pressure sensor is obtained.
