The utility model belongs to the technical field of welding equipment, and discloses a low frequency acoustic field controlled swing arc tungsten argon arc welding device, including a welding torch, a gas shield connected with the welding torch, a tungsten pole, a connecting piece connecting the tungsten pole and the welding torch, a guide rod connected with the tungsten pole, and a sound wave generator connected with the other end of the guide rod. The welding torch is provided with an electrical connection port, and an air hood is provided with an air inlet. The technical scheme combines acoustic wave with tungsten argon arc welding. The acoustic wave generated by the acoustic generator is transmitted to the tungsten pole through the guide rod, and the tungsten pole drives the arc to move as a pendulum. The wobbling of tungsten pole is beneficial to the heating of side wall by arc, which improves the problems of cold wall defects and side wall fusion which are difficult to overcome in the original narrow gap welding technology. At the same time, it simplifies the complex structure of the original narrow gap welding equipment, reduces the cost of equipment, reduces the spatter, overcomes the problem of poor formation of narrow gap GMAW welding seam, and achieves high efficiency welding and high weld forming efficiency. \u3002 The utility model is used for narrow gap welding.

技术介绍
随着现代工业日趋大型化,厚板、超厚板结构的应用愈来愈广泛。在舰艇、压力容器、锅炉、铁轨等金属结构产品的制造和大型工程建造现场作业中,厚板接头的传统自动焊接方法普遍采用大坡口多层多道焊或埋弧焊,焊接效率低、焊材消耗大、焊接成本高,已经不能满足现代工业对焊接的要求。窄间隙焊接是一种高效节能的焊接方法,采用窄坡口,能够大量地减少焊材使用量,不仅能够降低焊接成本,而且能够提高焊接效率,节约能源,已经成功应用于压力容器、船身等厚件的焊接。窄间隙焊接在核电、航天、造船、桥梁、建筑等领域有着广阔的应用前景,但其也存在着许多问题需要解决,包括坡口两侧冷壁缺陷、侧壁熔合不良,焊接飞溅,需要特殊焊接设备成本高等,限制了其实际应用。因此,提供一种实现侧壁熔合优良、避免焊接飞溅的焊接装置是很有必要的。
