The invention provides a machining method of bent contact tubes and belongs to the technical field of contact tube machining in melting electrode electric arc welding. According to the machining method of the bent contact tubes, the problem that the bent contact tubes which are relied on for achieving rotating electric arcs are not prone to being obtained or high in obtaining cost is solved. The machining method of the bent contact tubes conducts re-machining on the basis of linear contact tubes, geometric notches are machined in the outer surfaces of the side walls of the linear contact tubes, then the geometric notches are each subjected to three-point bending, and thus the bent contact tubes are conducted. The machining method of the bent contact tubes is used for obtaining the bent contact tubes. 弯曲导电嘴的加工方法，属于熔化极电弧焊接中导电嘴的加工技术领域。本发明是为了解决旋转电弧的实现所依赖的弯曲导电嘴不易获取，或者获取成本高的问题。它基于直线导电嘴进行再加工，所述方法在直线导电嘴的侧壁外表面加工几何缺口，然后在几何缺口处做三点弯曲，获得弯曲导电嘴。本发明用于获得弯曲导电嘴。
