The emergence of welding robot has brought great convenience to the user's welding process. In the process of using welding robot to carry out GMAW, the wire feeding process is basically in place in one step. That's because the welding robot is equipped with an automatic wire feeding system, including wire feeding, wire feeding hose, wire coil and other parts. The wire is sent to the welding machine through perfect configuration Specify the location.

焊接机器人的送丝系统可以通过三种不同的方式送丝，一种是推丝式，这样的结构相对比较简单、轻便，操作维修也很方便，但就是焊丝送进的阻力较大，随着送丝软管的加长，送丝稳定性变差。所以，这种送丝方式通常应用于焊丝直径为2.0mm、送丝软管长度为5m的半自动熔化极气体保护焊中。

The wire feeding system of welding robot can feed wire in three different ways. One is push wire type. This structure is relatively simple, light and easy to operate and maintain. However, the resistance of wire feeding is large. With the extension of wire feeding hose, the stability of wire feeding becomes worse. Therefore, this wire feeding method is usually used in semi-automatic GMAW with wire diameter of 2.0 mm and wire feeding hose length of 5 m.

焊接机器人送丝系统用到的另一种送丝方式是拉丝式，将焊丝盘和焊枪分开，使得两者通过送丝软管连接。另一种是将焊丝盘直接安装在焊枪上。这两种都适用于细丝半自动熔化极气体保护焊，使用焊丝直径小于或等于0.8mm，送丝较稳定。

Another wire feeding method used in welding robot wire feeding system is wire drawing type, which separates the welding wire coil and welding gun, so that they are connected through wire feeding hose. The other is to install the welding coil directly on the welding gun. Both of them are suitable for thin wire semi-automatic GMAW. The diameter of welding wire is less than or equal to 0.8mm, and the wire feeding is stable.

还有一种是推拉丝式送丝方式，也是焊接机器人送丝系统中会用到的工作方式，这种送丝系统中同时有推丝机和拉丝机，其中推丝为主要动力，拉丝是将焊丝校直。虽然它的送丝软管可加长到10m，但由于结构复杂，所以实际中用的并不多。

There is also a push-pull wire feeding mode, which is also used in the welding robot wire feeding system. In this wire feeding system, there are both push wire machine and wire drawing machine, in which push wire is the main power, and wire drawing is to straighten the welding wire. Although its wire feeding hose can be lengthened to 10m, it is not widely used in practice due to its complex structure.

既然送丝是焊接过程中不必可少的作业环节之一，那就要好好处理，在设计焊接机器人的时候也要将这方面考虑在内，使其送丝系统满足实际焊接的需求。

Since wire feeding is one of the indispensable operation links in the welding process, it is necessary to deal with it well. This aspect should also be taken into account when designing the welding robot, so that the wire feeding system can meet the actual welding needs.
