摘要： A threading method for threading a work 18 includes a supporting portion moving-up step for moving a supporting portion 17 upward by a predetermined distance by using an elevational mechanism 15 without rotating a tap 20 inserted into the work 18. Thus, the bent state of the robot arm 11 can be eliminated by moving the supporting portion 17 upward. In this case, since the supporting portion 17 is moved upward artificially, the supporting portion 17 can be moved up in a short time. That is, the bent state of the robot arm 11 can be eliminated in a short time and so the processing efficiency of the threading step can be improved.
摘要翻译： 用于穿线工件18的穿线方法包括支撑部分移动步骤，用于通过使用升降机构15将支撑部分17向上移动预定距离，而不旋转插入工件18中的龙头20。因此，弯曲状态 可以通过向上移动支撑部17来消除机器人手臂11。 在这种情况下，由于支撑部分17被人为地向上移动，支撑部分17可以在短时间内向上移动。 也就是说，可以在短时间内消除机器人手臂11的弯曲状态，从而可以提高穿线步骤的处理效率。

摘要： A magnetic field is generated in a workpiece in a direction orthogonal to the joining direction, and as a result of the Lorentz force resulting from the magnetic field and the current between the plasma torch and the workpiece, the front tip side of the arc is bent forward in the direction of advancement of the plasma torch and welding is performed. The magnetic field strength of the welded part is adjusted by changing the relative positions of the plasma torch and a butting portion of the workpiece.

摘要： A two-electrode arc welding device and two-electrode arc welding method are provided for performing welding with improved penetration performance using two non-consumable electrodes. In a two-electrode arc welding device, a power-supply unit outputs a straight-polarity voltage and a reverse-polarity voltage, which has a different electrical potential than the straight-polarity voltage. The straight-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. The reverse-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. An arc spacing distance, which is a distance between the ends of both the straight-polarity arc torch and the reverse-polarity arc torch, is set to be at least a minimum distance at which an arc will not occur therebetween (arc spacing critical distance).
