1、 Automatic welding equipment is used in all position welding, and the welding executive parts are driven by rotating pair to change the welding torch posture flexibly and reasonably, which is conducive to all position welding. At the same time, the motor power can be reduced when driving the same welding actuator. In the application, it is better to install the sensor on the welding position on the final reduction shaft, so as to detect the position of the welding gun. With this installation method, the control accuracy is relatively high.

此外，借助于全自动焊接设备上这一存储器，对部分焊接工艺的参数以及焊缝跟踪控制程序等进行存储，将焊接工艺参数储存于弧焊电源中，以此使弧焊电源所具优势更好地发挥，通过两者配合，有效地解决在全位置自动焊接作业中可能出现的各种质量问题。

In addition, with the aid of the memory on the automatic welding equipment, some welding process parameters and weld tracking control program are stored, and the welding process parameters are stored in the arc welding power source, so that the advantages of the arc welding power source can be better played. Through the cooperation of the two, various quality problems that may appear in the all position automatic welding operation can be effectively solved.

二，在焊枪驱动上借助于步进电机（步进电机是指把电脉冲信号转变成为角位移或者线位移的一种开环控制元步进电机件）来实施驱动，这种电机可把数字输入脉冲型号进行有效地转换，将其转换成为一种旋转运动，该元件自身的精度高，不仅不会出现漂移问题，同时也不会出现累计误差等问题。在全位置焊接中应用这一元件，不仅不会使转速发生改变，同时控制频率信号也比稳定，焊枪位移也更为准确。

2、 The welding torch is driven by stepping motor (stepping motor is a kind of open-loop control unit that converts the electric pulse signal into angular displacement or linear displacement). This kind of motor can effectively convert the digital input pulse type into a kind of rotary motion. The precision of the component itself is high, and there is no drift problem, At the same time, there will be no cumulative error and other problems. The application of this element in all position welding not only does not change the rotation speed, but also makes the control frequency signal more stable and the welding torch displacement more accurate.

三，在全位置焊接作业中，将焊接机头与弧焊电源有机结合，不仅能够达到全位置自动焊接的目的，同时在一定程度上还可使自动焊接设备得到降低。通过这种方式，不仅能够实现自动焊接，同时还可借助于弧焊电源以及半自动焊枪的利用来实施半自动焊接。

3、 In all position welding operation, the organic combination of welding head and arc welding power source can not only achieve the purpose of all position automatic welding, but also reduce the price of automatic welding equipment to a certain extent. In this way, not only automatic welding can be realized, but also semi-automatic welding can be realized with the help of arc welding power source and semi-automatic welding gun.
