摘要/Abstract

摘要： 为解决高氮钢熔焊过程中出现的气孔和氮损失问题，采用激光-电弧复合焊接技术对高氮钢进行焊接试验。研究了保护气体成分、焊丝成分和超声振动对焊接接头气孔率和氮含量的影响。结果表明：当保护气体为Ar+N₂时，随着保护气体中N₂比例的增大，焊缝氮含量升高，气孔率呈先降低、后升高的趋势；当向Ar+N₂中添加2%的O₂后，氮含量和气孔率明显升高，且随着N₂比例的增大，焊缝氮含量增多，但气孔率呈无规律变化；随着焊丝氮含量的增加，焊缝氮含量呈先升高、后降低趋势，气孔率呈先降低、后升高趋势；随着超声功率的增加，焊缝氮含量略有降低，气孔率呈先降低、后升高趋势；适当的保护气体和焊丝成分可提高焊缝氮含量的同时并能够抑制焊缝气孔形成，超声功率为180 W时抑制气孔效果最好。

Abstract: The laser-arc hybrid welding test of high nitrogen steel was carried out to solve the porosity and nitrogen loss of high nitrogen steel during welding. The effects of shielding gas composition, welding wire composition and ultrasonic vibration on the porosity and nitrogen content of welded joint were investigated. The results show that, when the shielding gas is Ar+N₂, the nitrogen content of welded point increases with the proportion of nitrogen in the shielding gas, and the porosity decreases first and then increases. When 2% O₂ is added to Ar+N₂, the nitrogen content and porosity increase obviously. With the increase in the proportion of nitrogen, the nitrogen content in welded joint increases, but the porosity changes irregularly. With the increase in nitrogen content in the welding wire, the nitrogen content of welded joint increases first and then decreases, and the porosity decreases first and then increases. With the increase in ultrasonic power, the nitrogen content of welded joint decreases slightly, and the porosity decreases first and then increases. Appropriate shielding gas and welding wire composition can be used to improve the nitrogen content of welded joint, and inhibit the formation of weld porosity. The porosity is suppressed in the best effect when the ultrasonic power is 180 W. Key
