文中主要对高氮奥氏体不锈钢专用焊丝焊接过程的稳定性进行研究，分析了不同氮含量焊丝的电流电压信号，并用高速摄像和汉诺威质量检测分析仪分析焊接过程的熔滴过渡.结果表明，随焊丝含氮量增加，焊接过程中虽然存在飞溅现象，但焊接过程更加稳定，这是由于为了使焊后熔敷金属为全奥氏体组织，将焊丝的含氮量增高的同时，减少Ni元素的加入，提高Mn元素含量，从而使熔滴的表面张力增加，焊接过程稳定性相对提高，并且在N元素和合金元素共同作用下，焊丝的喷射过渡临界电流降低，射滴过渡和射流过渡更加容易发生.
In order to analyze the stability of the special welding wires for high nitrogen stainless steel, high-speed camera was used to track the droplet transfer morphology and analyzer of Hannover was used to evaluate the droplet transfer. The results show that although weld spatter produced along with the increase of nitrogen content, the stability of the droplet transfer and the signals of currents and voltages are improved. This is because to make deposited metal astenitized, the Ni content was reduced while the Mn content was increased with increasing nitrogen content, so that surface tension of the material was improved. And the adjustment of elements reduces the critical current of spray transfer so that the spray transfer is more likely to happen.
