在全位置焊中应用自动焊接设备，焊接执行部件采取旋转副驱动的方式，对焊枪姿态进行灵活且合理地改变，有利于全位置焊接工作的进行。同时在驱动相同焊接执行部件的时候，还可减小电机功率。在应用中，将焊接位置上传感器安装于末级减速轴，以此对焊枪位置进行检测，采取这种安装方式，所获控制精度相对较高。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。

Applying automatic welding equipment in all position welding, the welding execution components are driven by rotating pairs to flexibly and reasonably change the posture of the welding gun, which is conducive to the progress of all position welding work. At the same time, when driving the same welding execution components, the motor power can also be reduced. In application, installing sensors at the welding position on the final reduction shaft to detect the welding gun position can achieve relatively high control accuracy. In addition, with the help of this memory on fully automatic welding equipment, some welding process parameters and weld seam tracking control programs are stored, and the welding process parameters are stored in the arc welding power source, so as to better utilize the advantages of the arc welding power source. Through the combination of the two, various quality problems that may occur in all position automatic welding operations can be effectively solved.、

第二，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，该元件自身的精度较高，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较稳定，焊枪位移也更为准确。

Secondly, in the welding gun drive, a stepper motor (which refers to an open-loop control element stepper motor component that converts electrical pulse signals into angular or linear displacement) is used to implement the drive. This motor can effectively convert the digital input pulse model into a rotary motion, and the component itself has high accuracy. It not only does not have drift problems, but also does not have cumulative errors and other problems. Applying this component in all position welding not only does not change the rotational speed, but also stabilizes the frequency signal and makes the welding gun displacement more accurate.

第三，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。

Thirdly, in all position welding operations, combining the welding machine head with the arc welding power source can not only achieve the goal of automatic welding in all positions, but also to some extent reduce the price of automatic welding equipment. Through this method, not only can automatic welding be achieved, but semi-automatic welding can also be carried out with the help of arc welding power sources and semi-automatic welding guns.
