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.

焊接機器人的送絲系統(tǒng)可以通過三種不同的方式送絲，一種是推絲式，這樣的結(jié)構(gòu)相對比較簡單、輕便，操作維修也很方便，但就是焊絲送進的阻力較大，隨著送絲軟管的加長，送絲穩(wěn)定性變差。所以，這種送絲方式通常應(yīng)用于焊絲直徑為2.0mm、送絲軟管長度為5m的半自動熔化極氣體保護焊中。

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.

焊接機器人送絲系統(tǒng)用到的另一種送絲方式是拉絲式，將焊絲盤和焊槍分開，使得兩者通過送絲軟管連接。另一種是將焊絲盤直接安裝在焊槍上。這兩種都適用于細絲半自動熔化極氣體保護焊，使用焊絲直徑小于或等于0.8mm，送絲較穩(wěn)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.

還有一種是推拉絲式送絲方式，也是焊接機器人送絲系統(tǒng)中會用到的工作方式，這種送絲系統(tǒng)中同時有推絲機和拉絲機，其中推絲為主要動力，拉絲是將焊絲校直。雖然它的送絲軟管可加長到10m，但由于結(jié)構(gòu)復雜，所以實際中用的并不多。

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.

既然送絲是焊接過程中不必可少的作業(yè)環(huán)節(jié)之一，那就要好好處理，在設(shè)計焊接機器人的時候也要將這方面考慮在內(nèi)，使其送絲系統(tǒng)滿足實際焊接的需求。

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.
